The persistent_config option is used to make the CEC settings persistent by using
the eeprom inside the device to store this information. This was on by default, which
caused confusion since this device now behaves differently from other CEC devices
which all come up unconfigured.
Another reason for doing this now is that I hope a more standard way of selecting
persistent configuration will be created in the future. And for that to work all
CEC drivers should behave the same and come up unconfigured by default.
None of the open source CEC applications are using this CEC framework at the moment
so change this behavior before it is too late.

The recent changes in 4.9 to mandate USB buffers be heap allocated
broke this driver, which was allocating the buffers on the stack.
This resulted in the device failing at initialization.
Introduce dedicated send/receive buffers as part of the state
structure, and add a mutex to protect access to them.
Note: we also had to tweak the API to mxl111sf_ctrl_msg to pass
the pointer to the state struct rather than the device, since
we need it inside the function to access the buffers and the
mutex. This patch adjusts the callers to match the API change.

On this driver, it can fall through a switch. I tried to
annotate it, in order to shut up a gcc warning, but that
didn't work, as the logic there is somewhat complex.
So, instead, let's just repeat the code. gcc should likely
optimize it anyway, and this makes the code better readable,
IMHO.

The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.
Move those sources to media/cec as well.
The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.
Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).
Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.
CEC drivers should now depend on CEC_CORE.
CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.
The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

driver/setup is very low and therefore not worth the efforts.
Instead, just don't treat the device as camera.
A message will then be printed to the log that the device isn't supported.

Use i2c_smbus_read_word_data() instead of i2c_master_send() and
i2c_master_recv() for reading the ID of Micorn sensors.
i2c_smbus_read_word_data() assumes that byes are in little-endian,
so, it uses:
data->word = msgbuf1[0] | (msgbuf1[1] << 8);
However, Micron datasheet describes the ID as if they were read
in big-endian. So, we need to change the byte order in order to
match the ID number as described on their datasheets.

On Kernel 4.9, WARNINGs about doing DMA on stack are hit at
the dw2102 driver: one in su3000_power_ctrl() and the other in tt_s2_4600_frontend_attach().
Both were due to the use of buffers on the stack as parameters to
dvb_usb_generic_rw() and the resulting attempt to do DMA with them.
The device was non-functional as a result.
So, switch this driver over to use a buffer within the device state
structure, as has been done with other DVB-USB drivers.
Tested with TechnoTrend TT-connect S2-4600.

We can avoid doing this by open-coding the call to i2c_transfer()

The driver uses a relatively large data structure on the stack, which
showed up on my radar as we get a warning with the "latent entropy"
GCC plugin:
drivers/media/usb/pvrusb2/pvrusb2-eeprom.c:153:1: error: the frame size of 1376 bytes is larger than 1152 bytes [-Werror=frame-larger-than=]
The warning is usually hidden as we raise the warning limit to 2048
when the plugin is enabled, but I'd like to lower that again in the
future, and making this function smaller helps to do that without
build regressions.
Further analysis shows that putting an 'i2c_client' structure on
the stack is not really supported, as the embedded 'struct device'
is not initialized here, and we are only saved by the fact that
the function that is called here does not use the pointer at all.

Pull media fix from Mauro Carvalho Chehab:
"A regression fix that makes the Siano driver to work again after the
CONFIG_VMAP_STACK change"
* tag 'media/v4.10-5' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
[media] siano: make it work again with CONFIG_VMAP_STACK
Reported as a Kaffeine bug:
https://bugs.kde.org/show_bug.cgi?id=375811
The USB control messages require DMA to work. We cannot pass
a stack-allocated buffer, as it is not warranted that the
stack would be into a DMA enabled area.
On Kernel 4.9, the default is to not accept DMA on stack anymore
on x86 architecture. On other architectures, this has been a
requirement since Kernel 2.2. So, after this patch, this driver
should likely work fine on all archs.

If the USB driver is enabled but the demodulator is not, we get a link error:
ERROR: "zd1301_demod_get_dvb_frontend" [drivers/media/usb/dvb-usb-v2/zd1301.ko] undefined!
ERROR: "zd1301_demod_get_i2c_adapter" [drivers/media/usb/dvb-usb-v2/zd1301.ko] undefined!
Such a configuration obviously makes no sense, but we should not fail
the build. This tries to mimic what we have for other drivers by turning
the build failure into a runtime failure.
Alternatively we could use an unconditional 'select' or 'depends on' to enforce
a sane configuration.

added a kmalloc'ed bounce buffer for writes, but missed to do the same
for reads. As the read only happens after the write is finished, we can
reuse the same buffer.
As dvb_usb_generic_rw handles a read length of 0 by itself, avoid calling
it using the dvb_usb_generic_read wrapper function.

I ran into a stack frame size warning because of the on-stack copy of
the USB device structure:
drivers/media/usb/dvb-usb-v2/dvb_usb_core.c: In function 'dvb_usbv2_disconnect':
drivers/media/usb/dvb-usb-v2/dvb_usb_core.c:1029:1: error: the frame size of 1104 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Copying a device structure like this is wrong for a number of other reasons
too aside from the possible stack overflow. One of them is that the
dev_info() call will print the name of the device later, but AFAICT
we have only copied a pointer to the name earlier and the actual name
has been freed by the time it gets printed.
This removes the on-stack copy of the device and instead copies the
device name using kstrdup(). I'm ignoring the possible failure here
as both printk() and kfree() are able to deal with NULL pointers.

The STK1160 needs some time to transfer data to and from the AC97 codec.
The transfer completion is indicated by command read/write bits in the
chip's audio control register. The driver should poll these bits and
wait until they have been cleared by hardware before trying to retrieve
the results of a read operation or setting a new write command.

Some STK1160-based devices use the chip's internal 8-bit ADC. This is
configured through a strap pin. The value of this and other pins can be
read through the POSVA register. If the internal ADC is used, or if
audio is disabled altogether, there's no point trying to setup the AC97
codec.

Exposing all the channels of the device's internal AC97 codec to
userspace is unnecessary and confusing. Instead the driver should setup
the codec with proper values. This patch removes the mixer and sets up
the codec using optimal values, i.e. the same values set by the Windows
driver. This also makes the device work out-of-the-box, without the need
for the user to reconfigure the device every time it's plugged in.

Drivers might try to access and run enable_source and disable_source
handlers when the driver that implements these handlers is clearing
the handlers during its unregister.
Fix the following race condition:
process 1 process 2
request video streaming unbind au0828
v4l2 checks if tuner is free
... ...
au0828_unregister_media_device()
... ...
(doesn't hold graph_mutex)
mdev->enable_source = NULL;
if (mdev && mdev->enable_source) mdev->disable_source = NULL;
mdev->enable_source()
(enable_source holds graph_mutex)
As shown above enable_source check is done without holding the graph_mutex.
If unbind happens to be in progress, au0828 could clear enable_source and
disable_source handlers leading to null pointer de-reference.
Fix it by protecting enable_source and disable_source set and clear and
protecting enable_source and disable_source handler access and the call
itself.
process 1 process 2
request video streaming unbind au0828
v4l2 checks if tuner is free
... ...
au0828_unregister_media_device()
... ...
(hold graph_mutex while clearing)
mdev->enable_source = NULL;
if (mdev) mdev->disable_source = NULL;
(hold graph_mutex to check and
call enable_source)
if (mdev->enable_source)
mdev->enable_source()
If graph_mutex is held to just heck for handler being null and needs to be
released before calling the handler, there will be another window for the
handlers to be cleared. Hence, enable_source and disable_source handlers
no longer hold the graph_mutex and expect callers to hold it to avoid
forcing them release the graph_mutex before calling the handlers.

The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.
This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.
Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

The media_entity_pipeline_start() and media_entity_pipeline_stop()
functions are renamed as media_pipeline_start() and media_pipeline_stop(),
respectively. The reason is two-fold: the pipeline struct is, rightly,
already called media_pipeline (rather than media_entity_pipeline) and what
this really is about is a pipeline. A pipeline consists of entities ---
and, well, other objects embedded in these entities.
As the pipeline object will be in the future moved from entities to pads
in order to support multiple pipelines through a single entity, do the
renaming now.
Similarly, functions operating on struct media_entity_graph as well as the
struct itself are renamed by dropping the "entity_" part from the prefix
of the function family and the data structure. The graph traversal which
is what the functions are about is not specifically about entities only
and will operate on pads for the same reason as the media pipeline.
The patch has been generated using the following command:
git grep -l media_entity |xargs perl -i -pe '
s/media_entity_pipeline/media_pipeline/g;

tt3650_ci_msg_locked() has already locked the mutex.
So, partially revert it, but move the buffer to the heap
(DMA capable), not to the stack (may not be DMA capable).
Instead of sharing one buffer which needs mutex protection,
do a new heap allocation for each call.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.

adjusted if needed.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually
adjusted if needed.

The dvb_filter.c can hardly be considered as part of the DVB
core. More than half of the code there is commented out by
av7110 and ttusb_dec.
On the latter, just two small helper functions and a struct
definition is used.
Being part of the core means that it would require an
amount of work to fix issues in it, like bad printk's
on it, and to document it on some future, like other kAPI
headers. It simply not worth the effort for something that
seems to be deprecated, as no new drivers use it.
So, move it out of the core, by moving it to pci/ttpci
directory, where av7110 driver is kept, and copy the two
routines used by ttyusb_dec directly into its code.

There are still several places with printk's called directly.
Convert them to pr_foo() macros, except for the debug printk's,

Instead of sending USB commands for every stats call, collect
them once, when status is updated. As the frontend kthread
will call it on every few seconds, the stats will still be
collected.
Besides reducing the amount of USB/I2C transfers, this also
warrants that all stats will be collected at the same time,
and makes easier to convert it to DVBv5 stats in the future.

Tha ARM randconfig builds came up with another rare build failure

Apparently this used to be a valid configuration (build-time, not
run-time), but broke as part of a cleanup.
I tried reverting the cleanup, but saw that the code was still wrong
then. This version adds a dependency for dib3000mb, to ensure that
dib3000mb does not force the dibusb_dib3000mc_frontend_attach function
to be built-in when dib3000mc is a loadable module.
I have also checked the two other files that were changed in the original
cleanup, and found them to be correct in either version, so I do not
touch that part.
As this is a rather obscure bug, there is no need for backports.

The workqueue "work_thread" is involved in streaming the camera data.
It has a single work item(&dev->work_struct) and hence doesn't require
ordering. Also, it is not being used on a memory reclaim path.
Hence, the singlethreaded workqueue has been replaced with the use of
system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
Work item has been flushed in sd_stop0() to ensure that there are no
pending tasks while disconnecting the driver.

Fix a memory leak on probe error of the airspy usb device driver.
The problem is triggered when more than 64 usb devices register with
v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV.
The memory leak is caused by the probe function of the airspy driver
mishandeling errors and not freeing the corresponding control structures
when an error occours registering the device to v4l2 core.
A badusb device can emulate 64 of these devices, and then through
continual emulated connect/disconnect of the 65th device, cause the
kernel to run out of RAM and crash the kernel, thus causing a local DOS
vulnerability.

The value 5 of the EEPROM_TS_MODE register (meaning dual tuner presence) is
only valid for AF9035 devices. For IT9135 devices it is invalid and led to a
false positive dual tuner mode detection with PCTV 79e.
Therefore on non-AF9035 devices and with value 5 the driver now defaults to
single tuner mode and outputs a regarding info message to log.
This fixes Bugzilla bug #118561.

When disconnecting the usbtv device, the sound card is unregistered
from ALSA and the snd member of the usbtv struct is set to NULL. If
the usbtv snd_trigger work is running, this can cause a race condition
where the kernel will attempt to access free'd resources, shown in
[1].
This patch fixes the disconnection code by cancelling any snd_trigger
work before unregistering the sound card from ALSA and checking that
the snd member still exists in the work function.

Converts the dtt200u DVB USB driver over to the rc-core
infrastructure for its handling of IR remotes. This device can receive
generic NEC / NEC Extended signals and the switch to the newer core

struct media_devnode is currently embedded at struct media_device.
While this works fine during normal usage, it leads to a race
condition during devnode unregister. the problem is that drivers
assume that, after calling media_device_unregister(), the struct
that contains media_device can be freed. This is not true, as it
can't be freed until userspace closes all opened /dev/media devnodes.
In other words, if the media devnode is still open, and media_device
gets freed, any call to an ioctl will make the core to try to access
struct media_device, with will cause an use-after-free and even GPF.
Fix this by dynamically allocating the struct media_devnode and only
freeing it when it is safe.

Pull string hash improvements from George Spelvin:
"This series does several related things:
- Makes the dcache hash (fs/namei.c) useful for general kernel use.
(Thanks to Bruce for noticing the zero-length corner case)
- Converts the string hashes in <linux/sunrpc/svcauth.h> to use the
above.
- Avoids 64-bit multiplies in hash_64() on 32-bit platforms. Two
32-bit multiplies will do well enough.
- Rids the world of the bad hash multipliers in hash_32.
This finishes the job started in commit 689de1d6ca ("Minimal
fix-up of bad hashing behavior of hash_64()")
The vast majority of Linux architectures have hardware support for
32x32-bit multiply and so derive no benefit from "simplified"
multipliers.
The few processors that do not (68000, h8/300 and some models of
Microblaze) have arch-specific implementations added. Those
patches are last in the series.
- Overhauls the dcache hash mixing.
The patch in commit 0fed3ac866 ("namei: Improve hash mixing if
CONFIG_DCACHE_WORD_ACCESS") was an off-the-cuff suggestion.
Replaced with a much more careful design that's simultaneously
faster and better. (My own invention, as there was noting suitable
in the literature I could find. Comments welcome!)
- Modify the hash_name() loop to skip the initial HASH_MIX(). This
would let us salt the hash if we ever wanted to.
- Sort out partial_name_hash().
The hash function is declared as using a long state, even though
it's truncated to 32 bits at the end and the extra internal state
contributes nothing to the result. And some callers do odd things:
- fs/hfs/string.c only allocates 32 bits of state
- fs/hfsplus/unicode.c uses it to hash 16-bit unicode symbols not bytes
- Modify bytemask_from_count to handle inputs of 1..sizeof(long)
rather than 0..sizeof(long)-1. This would simplify users other
than full_name_hash"
Special thanks to Bruce Fields for testing and finding bugs in v1. (I
learned some humbling lessons about "obviously correct" code.)
On the arch-specific front, the m68k assembly has been tested in a
standalone test harness, I've been in contact with the Microblaze
maintainers who mostly don't care, as the hardware multiplier is never
omitted in real-world applications, and I haven't heard anything from
the H8/300 world"
* 'hash' of git://ftp.sciencehorizons.net/linux:
h8300: Add <asm/hash.h>
microblaze: Add <asm/hash.h>
m68k: Add <asm/hash.h>
<linux/hash.h>: Add support for architecture-specific functions
fs/namei.c: Improve dcache hash function
Eliminate bad hash multipliers from hash_32() and hash_64()
Change hash_64() return value to 32 bits
<linux/sunrpc/svcauth.h>: Define hash_str() in terms of hashlen_string()
fs/namei.c: Add hashlen_string() function
Pull out string hash to <linux/stringhash.h>
The "simplified" prime multipliers made very bad hash functions, so get rid
of them. This completes the work of 689de1d6ca.
To avoid the inefficiency which was the motivation for the "simplified"
multipliers, hash_64() on 32-bit systems is changed to use a different
algorithm. It makes two calls to hash_32() instead.
drivers/media/usb/dvb-usb-v2/af9015.c uses the old GOLDEN_RATIO_PRIME_32
for some horrible reason, so it inherits a copy of the old definition.

Hauppauge WinTV-dualHD is a USB 2.0 dual DVB-T/T2/C tuner with
following components:
USB bridge: Empia EM28274 (chip id is the same as EM28174)
Demodulator: 2x Silicon Labs Si2168-B40
Tuner: 2x Silicon Labs Si2157-A30
This patch adds support only for the first tuner.
The demodulator needs firmware, available for example here:
http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/
The demodulators sit on the same I2C bus and their addresses
are 0x64 and 0x67. The tuners are behind the demodulators and
their addresses are 0x60 and 0x63.

The root i2c adapter lock is then no longer held by the i2c mux during
accesses behind the i2c gate, and such accesses need to take that lock
just like any other ordinary i2c accesses do.
So, declare the i2c gate mux-locked, and zap the regmap overrides
that makes the i2c accesses unlocked and use plain old regmap
accesses. This also removes the need for the regmap wrappers used by
rtl2832_sdr, so deconvolute the code further and provide the regmap
handle directly instead of the wrapper functions.

The v4l2_device_call_* defines filter subdevs based on the grp_id value.
But some drivers use a bitmask, so instead of filtering by grp_id == value,
you want to filter by grp_id & value.
Make variants of these defines to do this.
The 'has_op' define has been extended to have a grp_id argument as well, and
a mask variant has been added.
This extra argument required a change to go7007.

Commit 588afcc1c0 ("[media] usbvision fix overflow of interfaces

* "!dev->actconfig->interface[ifnum]" won't catch a case where the value
is not NULL but some garbage. This way the system may crash later with
GPF.
* "(ifnum >= USB_MAXINTERFACES)" does not cover all the error
conditions. "ifnum" should be compared to "dev->actconfig->
desc.bNumInterfaces", i.e. compared to the number of "struct
usb_interface" kzalloc()-ed, not to USB_MAXINTERFACES.
* There is a "struct usb_device" leak in this error path, as there is
usb_get_dev(), but no usb_put_dev() on this path.
* There is a bug of the same type several lines below with number of
endpoints. The code is accessing hard-coded second endpoint
("interface->endpoint[1].desc") which may not exist. It would be great
to handle this in the same patch too.

EMP202 chip inside Terratec Grabby (hw rev 2) seems to require some time
before accessing reliably its registers. Otherwise it returns some values
previously put on the I2C bus.
To account for that period, we delay card setup until we have a proof that
accessing AC97 registers is reliable. We get this proof by polling
AC97_RESET until the expected value is read. We also check that unrelated
registers don't return the same value. This second check handles the case
where the expected value is constantly returned no matter which register

Media device initialization and registration steps are split. There is a
window between media device init and media device register during usb
probe.
au0828 bridge driver and snd-usb-audio could try to initialize the media
device, if they simply checked, whether the device has been registered.
They also need to check whether the device has been initialized.
Change the au0828-core to check if media device is already initialized
during initialization step and check if media device is already
registered during the registration step.

Change au0828 to use Managed Media Controller API to share media device
and coordinate creating/deleting the shared media device with the
snd-usb-audio driver. The shared media device is created as device
resource of the parent usb device of the two drivers.
Populate media device model with USB Device product name instead of
au0828 device board name. This change is necessary because, if the media
device is registered by the snd-usb-audio driver first, and it doesn't

It makes sense to make the min_t() cast unsigned here since we don't
really want negative sizes. Making it signed causes a static checker
warning in Smatch. Smatch knows "fw->size - i" is positive but it
doesn't know that fw->size is less than INT_MAX so in theory casting it

This is needed because several drivers don't care enough to only

Pull second batch of media updates from Mauro Carvalho Chehab:
"This is the second part of the media patches. It contains the media
controller next generation patches, with is the result of one year of
discussions and development. It also contains patches to enable media
controller support at the DVB subsystem.
The goal is to improve the media controller to allow proper support
for other types of Video4Linux devices (radio and TV ones) and to
extend the media controller functionality to allow it to be used by
other subsystems like DVB, ALSA and IIO.
In order to use the new functionality, a new ioctl is needed
(MEDIA_IOC_G_TOPOLOGY). As we're still discussing how to pack the
struct fields of this ioctl in order to avoid compat32 issues, I
decided to add a patch at the end of this series commenting out the
new ioctl, in order to postpone the addition of the new ioctl to the
next Kernel version (4.6).
With that, no userspace visible changes should happen at the media
controller API, as the existing ioctls are untouched. Yet, it helps
DVB, ALSA and IIO developers to develop and test the patches adding
media controller support there, as the core will contain all required
internal changes to allow adding support for devices that belong to
those subsystems"

The media device node is registered and so made visible to user-space
before entities are registered and links created which means that the
media graph obtained by user-space could be only partially enumerated
if that happens too early before all the graph has been created.
To avoid this race condition, split the media init and registration
in separate functions and only register the media device node when
all the pending subdevices have been registered, either explicitly
by the driver or asynchronously using v4l2_async_register_subdev().
The media_device_register() had a check for drivers not filling dev
and model fields but all drivers in mainline set them and not doing
it will be a driver bug so change the function return to void and
add a BUG_ON() for dev being NULL instead.
Also, add a media_device_cleanup() function that will destroy the
graph_mutex that is initialized in media_device_init().

kind of link, so it can be removed.

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.
So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.
The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.

Entities should have one or more functions. Calling it as a
type proofed to not be correct, as an entity could eventually
have more than one type.
So, rename the field as function.
Please notice that this patch doesn't extend support for
multiple function entities. Such change will happen when
we have real case drivers using it.
No functional changes.

The entire logic that represent graph links were developed on a
time where there were no needs to dynamic remove links. So,
although links are created/removed one by one via some
functions, they're stored as an array inside the entity struct.
As the array may grow, there's a logic inside the code that
checks if the amount of space is not enough to store
the needed links. If it isn't the core uses krealloc()
to change the size of the link, with is bad, as it
leaves the memory fragmented.
So, convert links into a list.
Also, currently, both source and sink entities need the link
at the graph traversal logic inside media_entity. So there's
a logic duplicating all links. That makes it to spend
twice the memory needed. This is not a big deal for today's
usage, where the number of links are not big.
Yet, if during the MC workshop discussions, it was said that
IIO graphs could have up to 4,000 entities. So, we may
want to remove the duplication on some future. The problem
is that it would require a separate linked list to store
the backlinks inside the entity, or to use a more complex
algorithm to do graph backlink traversal, with is something
that the current graph traversal inside the core can't cope
with. So, let's postpone a such change if/when it is actually
needed.
It should also be noticed that the media_link structure uses
44 bytes on 32-bit architectures and 84 bytes on 64-bit
architecture. It will thus be allocated out of the 64-bytes and
96-bytes pools respectively. That's a 12.5% memory waste on
64-bit architectures and 31.25% on 32-bit architecture.
A linked list is less efficient than an array in this case, but
this could later be optimized if we can get rid of the reverse
links (with would reduce memory allocation by 50%).

With the new API, a link can be either between two PADs or between an interface

links between two pads.
So, rename the such function to media_create_pad_link().

Currently, media_entity_init() creates an array with the links,
allocated at init time. It provides a parameter (extra_links)
that would allocate more links than the current needs, but this
is not used by any driver.
As we want to be able to do dynamic link allocation/removal,
we'll need to change the implementation of the links. So,
before doing that, let's first remove that extra unused
parameter, in order to cleanup the interface first.

The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.
After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.
To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

Currently, include/media is messy, as it contains both the V4L2 core
headers and some driver-specific headers on the same place. That makes
harder to identify what core headers should be documented and what
headers belong to I2C drivers that are included only by bridge/main
drivers that would require the functions provided by them.
Let's move those i2c specific files to its own subdirectory.
The files to move were produced via the following script:
mkdir include/media/i2c
(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done
And the references corrected via this script:
MAIN_DIR="media/"
PREV_DIR="media/"

This is a preparation for a change to the type of v4l2 timestamps.
v4l2_get_timestamp() is a helper function that reads the monotonic
time and stores it into a 'struct timeval'. Multiple drivers implement
the same thing themselves for historic reasons.
Changing them all to use v4l2_get_timestamp() is more consistent
and reduces the amount of code duplication, and most importantly
simplifies the following changes.

This causes lots of problems and is *very* slow as well.
One of the main problems is that this prohibits the use of the control
framework since subdevs will be unloaded on power off which is not allowed
as long as they are used by a usb device.
Apparently the reason for doing this is to turn off a noisy tuner. My hardware
has no problem with that, and I wonder whether the hardware with that noisy
tuner wasn't just functioning improperly as I have never heard of noisy tuners.
Contact me if you have one of those devices and I can take a look whether the
tuner can't be powered off if necessary by letting the tuner subdevice go
into standby mode. Unloading the tuner module is just evil and is not the
right approach.

This commit implements frame decimation for stk1160, which allows
to support format changes instead of a static frame size.
The stk1160 supports independent row and column decimation, in two
different modes:
* set a number of rows/columns units to skip for each unit sent.
* set a number of rows/columns units to send for each unit skipped.
This effectively allows to achieve different frame scaling ratios.
The unit number can be set to either two row/columns sent/skipped,
or four row/columns sent/skipped. Since the video format (UYVY)
has 4-bytes, using a unit number of two row/columns results
in frame color 'shifting', so set to four row/columns sent/skipped.

The TS2020 and TS2022 tuners take an input from the demodulator indicating the
AGC setting on that component that is then used to influence the tuner's own
gain. This should be taken into account when calculating the gain and signal
strength.
Further, the existing TS2020 driver miscalculates the signal strength as the
result of its calculations can exceed the storage capacity of the 16-bit word
used to return it to userspace.
To this end:
(1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that
the tuner can call to get the AGC PWM value from the demodulator.
(2) Modify the TS2020 driver to calculate the gain according to Montage's
specification with the adjustment that we produce a negative value and
scale it to 0.001dB units (which is what the DVBv5 API will require):
(a) Callback to the demodulator to retrieve the AGC PWM value and then
turn that into Vagc for incorporation in the calculations. If the
callback is unset, assume a Vagc of 0.
(b) Calculate the tuner gain from a combination of Vagc and the tuner's RF
gain and baseband gain settings.
(3) Turn this into a percentage signal strength as per Montage's
specification for return to userspace with the DVBv3 API.
(4) Provide a function in the M88DS3103 demodulator driver that can be used to
get the AGC PWM value on behalf of the tuner.
(5) The ts2020_config.get_agc_pwm function should be set by the code that
stitches together the drivers for each card.
For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022,
set the get_agc_pwm function to point to m88ds3103_get_agc_pwm.
I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022.

these parts.

drivers/media/usb/tm6000/tm6000-video.c:646 tm6000_prepare_isoc() error: we previously assumed 'dev->urb_buffer' could be null (see line 624)
This is not really a problem, but it actually shows that the check
if urb_buffer is NULL is being done twice: at the if and at
tm6000_alloc_urb_buffers().
We don't need to do it twice. So, remove the extra check. The code

The UVC_DEV_DISCONNECTED flag is set when the USB device is
disconnected, and checked in the open() handler to refuse opening a
device that has been disconnected.
This is inherently racy, but the race condition is taken care of in the
V4L2 core, which also fails open() calls when the V4L2 device node has
been unregistered. As the uvcvideo USB disconnect handler unregisters
all its video device nodes, the UVC_DEV_DISCONNECTED flag doesn't serve
any purpose anymore and can be removed.

GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner.
It's based on the following components:
- USB bridge: RTL2832P (contains also DVB-T demodulator)
- Demodulator: Si2168-A30
- Tuner: Si2148-A20
The demodulator and the tuner will need firmwares. The Si2148 uses Si2158
firmware. Antti has the firmwares available for download:
http://palosaari.fi/linux/v4l-dvb/firmware/
Do note that for DVB-T either of the demodulators can be used. DVB-C and
DVB-T2 are only supported by the Si2168 demodulator. The driver will
register 2 frontends for the same adapter. Frontend 0 will be the RTL2832
demodulator and frontend 1 will be the Si2168 demodulator. The same
tuner is used for both.
As a consequence of the above, it's recommended to use application that
does implement proper DVBv5 support.
For some reason, the old I2C write method sporadically fails. Thus the
need for an option to only use the new I2C write method supported by the
RTL2832.

When an error happens, a break statement is enough to go out of

The v4l2-compliance tool expects that if VIDIOC_CROPCAP is defined, then
VIDIOC_G_SELECTION for TGT_CROP_BOUNDS/DEFAULT is also defined (or COMPOSE
in the case of an output device).
In fact, all that a driver has to do to implement cropcap is to support
those two targets since the v4l2 core will implement cropcap and fill in
the pixelaspect to 1/1 by default.
Implementing cropcap is only needed if the pixelaspect isn't square.
So implement g_selection instead of cropcap in uvc to fix the v4l2-compliance
failure.

videobuf2 has long been subject to AB-BA style deadlocks due to the
queue lock and mmap_sem being taken in different orders for the mmap and
get_unmapped_area operations. The problem has been fixed by making those
two operations callable without taking the queue lock, using an
mmap_lock internal to videobuf2.
The uvcvideo driver still calls the mmap and get_unmapped_area
operations with the queue lock held, resulting in a potential deadlock.
As the operations can now be called without locking the queue, fix it.

The cos table used at fixp-arith.h has only 8 bits of precision.
That causes problems if it is reused on other drivers.
As some media drivers require a higher precision sin/cos
implementation, replace the current implementation by one that
will provide 32 bits precision.
The values generated by the new implementation matches the
32 bit precision of glibc's sin for an angle measured in
integer degrees.
It also provides support for fractional angles via linear
interpolation. On experimental calculus, when used a table
with a 0.001 degree angle, the maximum error for sin is
0.000038, which is likely good enough for practical purposes.
There are some logic there that seems to be specific to the
usage inside ff-memless.c. Move those logic to there, as they're
not needed elsewhere.

au0828_analog_register() frees au0828_dev when it fails to
locate isoc endpoint. au0828_usb_probe() continues with dvb
and rc probe and registration assuming dev is still valid.
When au0828_analog_register() fails to locate isoc endpoint,
it should return without free'ing au0828_dev. Otherwise, the
probe will fail as dev is null when au0828_dvb_register() is
called.

The USB and MMC front-ends to the siano driver both only make

already requires RC_CORE to not be a module, so we also need
to add that dependency here.

changeset 5eeb301482 added a fixup at the error check
code. However, it introduced a new error:
drivers/media/usb/cx231xx/cx231xx-cards.c:1586 cx231xx_usb_probe() error: we previously assumed 'dev' could be null (see line 1430)
This happens when dev = kmalloc() fails. So, instead of relying
on it to succeed, just change the parameter of clear_bit() from
'dev->devno' to 'nr'.

Commit b7085c0864 ("cx231xx: convert from pr_foo to dev_foo")
moves usb_get_dev(interface_to_usbdev(interface)) to the beginning
of cx231xx_usb_probe() to use udev->dev in dev_err(),
but it does not make sure usbdev is put on all failure paths.
Later dev_err(udev->dev) was replaced by dev_err(d).
So the patch moves usb_get_dev() below (before the first use)
and fixes another failure path.

Add support in the PS3 Eye driver for QVGA capture at higher
frame rates: 187, 150, and 137 FPS. This functionality is valuable
because the PS3 Eye is popular for computer vision projects and no
other camera in its price range supports such high frame rates.
Correct a QVGA mode that was listed as 40 FPS. It is really 37 FPS
(half of 75 FPS).
Tests confirm that the nominal frame rates are achieved.

The UVC spec is a bit vague wrt devices using bulk endpoints,
specifically, how to signal to a device to start streaming.
For devices using isoc endpoints, the sequence for start streaming is:
1) The host sends PROBE_CONTROL(SET_CUR) PROBE_CONTROL(GET_CUR)
2) Host selects desired config and calls COMMIT_CONTROL(SET_CUR)
3) Host selects an alt interface other then zero - e.g SELECT_ALTERNATE_INTERFACE(1)
4) The device starts streaming
However for devices using bulk endpoints, there must be *no* alt interface
other than setting zero. From the UVC spec:
"A VideoStreaming interface containing a bulk endpoint for streaming shall
support only alternate setting zero. Additional alternate settings containing
bulk endpoints are not permitted in a device that is compliant with the Video
Class specification."
So for devices using bulk endpoints, step #3 above is irrelevant, and thus
cannot be used as an indication for the device to start streaming.
So in practice, such devices start streaming immediately after a
COMMIT_CONTROL(SET_CUR).
In the uvc resume() handler, an unsolicited commit is sent, which causes
devices using bulk endpoints to start streaming unintentionally.
This patch modifies resume() handler to send a commit only if streaming
needs to be reestablished, i.e if the device was actually streaming before is
was suspended.

The Magewell XI100DUSB-HDMI[1] video capture device reports the pixel
format "e436eb7d-524f-11ce-9f53-0020af0ba770". This is its GUID for
BGR 8:8:8.
The UVC 1.5 spec[2] only defines GUIDs for YUY2, NV12, M420 and I420.
This seems to be an extension documented in the Microsoft Windows Media
Format SDK[3] - or at least the Media Format SDK was the only hit that
Google gave when searching for the GUID. This Media Format SDK defines
this GUID as corresponding to `MEDIASUBTYPE_RGB24`. Note though, the
XI100DUSB outputs BGR e.g. byte-reversed. I don't know if its the
capture device in error or Microsoft mean BGR when they say RGB.

- Move drivers for really old legacy hardware to staging. Those are
using obsolete media kAPIs and are for hardware that nobody uses for
years. Simply not worth porting them to the new kAPIs. Of course,
if anyone pops up to fix, we can move them back from there
- While not too late, do some API fixups at the new colorspace API,
added for v3.19
- Some improvements for rcar_vin driver
- Some fixups at cx88 and vivid drivers
- Some Documentation fixups

This driver hasn't been tested in a long, long time. The company that made
this chip has gone bust many years ago and hardware using this chip is next
to impossible to find.
This driver needs to be converted to newer media frameworks but due to the
lack of hardware that's going to be impossible. Since cheap alternatives are
easily available, there is little point in keeping this driver alive.
In other words, this driver is a prime candidate for removal. If someone is
interested in working on this driver to prevent its removal, then please
contact the linux-media mailinglist.

Merge tag 'media/v3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- Two new dvb frontend drivers: mn88472 and mn88473
- A new driver for some PCIe DVBSky cards
- A new remote controller driver: meson-ir
- One LIRC staging driver got rewritten and promoted to mainstream:
igorplugusb
- A new tuner driver (m88rs6000t)
- The old omap2 media driver got removed from staging. This driver
uses an old DMA API and it is likely broken on recent kernels.
Nobody cared enough to fix it
- Media bus format moved to a separate header, as DRM will also use the
definitions there
- mem2mem_testdev were renamed to vim2m, in order to use the same
naming convention taken by the other virtual test driver (vivid)
- Added a new driver for coda SoC (coda-jpeg)
- The cx88 driver got converted to use videobuf2 core
- Make DMABUF export buffer to work with DMA Scatter/Gather and Vmalloc
cores
- Lots of other fixes, improvements and cleanups on the drivers.

This patch is basically produced while testing a tool that
Joe Perches sent upstream sometime ago:
https://lkml.org/lkml/2014/7/11/794
I used it with those arguments:
$ reformat_with_checkpatch.sh drivers/media/usb/em28xx/em28xx*.[ch]
It actually produced 24 patches, with is too much, and showed
interesting things: gcc produced different codes on most of the
patches, even with just linespace changes. The total code data
remained the same on all cases I checked though.
Anyway, provided that we fold the resulting patches, this tool
seems useful.

Drivers that use dvb_attach can have just one exported symbol,
or they will cause compilation breakages depending on the
selected frontends.
As Jim reported:
drivers/built-in.o: In function `technisat_usb2_set_voltage':
technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio'
make: *** [vmlinux] Error 1
That happens because, on his configuration, the configuration
is:
CONFIG_DVB_USB=y
CONFIG_DVB_STV090x=m
Luis proposed ar way to fix, but that would just force the
STV090x to be selected, even if one wants to use a device
with a different frontend.
Instead, let's do the right thing: move set_gpio to the
configuration structure and fill it during dvb_attach().
This way, the driver can still call it, and dvb_attach()
will load stv090x module only if the device really needs it.

* Empia EM28178 USB bridge
* Silicon Labs Si2168-A30 demodulator
* Silicon Labs Si2146-A10 tuner
I don't have the remote, so the RC_MAP is a best guess based on the pictures of

The cause is that uvc_status_cleanup() is called after usb_put_*() in
uvc_delete(). usb_put_*() removes the sysfs parent and eventually
removes the children recursively, so the later device_del() can't find
its sysfs. The fix is simply rearrange the call orders in
uvc_delete() so that the child is removed before the parent.

Unfortunately, on devices that have multiple interfaces, udev->dev
points to the parent device (usb) instead of the cx231xx specific one.
Due to that the logs don't look too nice, as they'll print messages
as if they were produced by USB core:
usb-1-2: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces
Instead of using the name of the parent device, let's use the name
of the first cx231xx interface for all cx231xx sub-modules.
With this path, the logs will be nicer:
cx231xx 1-2:1.1: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces

Now that we're using dev_foo, the logs become like:
usb 1-2: DVB: registering adapter 0 frontend 0 (Fujitsu mb86A20s)...
usb 1-2: Successfully loaded cx231xx-dvb
cx231xx: Cx231xx dvb Extension initialized
It is not clear, by the logs, that usb 1-2 name is an alias for
cx231xx. So, we also need to use dvb_info() at extension load/unload.
After the patch, it will print:
usb 1-2: Cx231xx dvb Extension initialized
With is coherent with the other logs.

There are lots of debug printks printed with pr_info. Also, the
printk's data are not too coherent:
- there are duplicated driver name at the print format;
- function name format string differs from function to function;
- long strings broken into multiple lines;
- some printks just produce ugly reports, being almost useless
as-is.
Do a cleanup on that.
Still, there are much to be done in order to do a better printk
job on this driver, but, at least it will now be a way less
verbose, if debug printks are disabled, and some logs might
actually be useful.

There is a new version of the TechnoTrend CT2-4400 USB tuner. The difference is the demodulator that is used (Si2168-B40 instead of -A30).
For TT CT2-4400v2 a TS stream related parameter needs to be set, otherwise the stream becomes corrupted. The Windows driver for both CT2-4400 and CT2-4400v2 sets this as well. After this patch the driver works for both versions.

This patches fixes an ancient bug in the dvb_usb_af9005 driver, which
has been reported at least in the following threads:
https://lkml.org/lkml/2009/2/4/350https://lkml.org/lkml/2014/9/18/558
If the driver is compiled in without any IR support (neither

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).
Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.
The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.
Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.

Commit e93e7fd9f5 ("v4l2: uvcvideo: Allow
using larger buffers") reworked the buffer size sanity check at buffer
completion time to use the frame size instead of the allocated buffer
size. However, it introduced two bugs in doing so:
- it assigned the allocated buffer size to the frame_size field, instead
of assigning the correct frame size
- it performed the assignment in the S_FMT handler, resulting in the
frame_size field being uninitialized if the userspace application
doesn't call S_FMT.
Fix both issues by removing the frame_size field and validating the
buffer size against the UVC video control dwMaxFrameSize.

Field has_audio in struct em28xx_audio_mode is used together with value
EM28XX_NO_AC97 of field ac97 to determine the internal type of audio
(none/i2s/ac97). This makes the code difficult to understand:
!audio_mode.has_audio && audio_mode.ac97 == EM28XX_NO_AC97 => no audio
!audio_mode.has_audio && audio_mode.ac97 != EM28XX_NO_AC97 => BUG
audio_mode.has_audio && audio_mode.ac97 == EM28XX_NO_AC97 => AC97 audio
audio_mode.has_audio && audio_mode.ac97 != EM28XX_NO_AC97 => I2S audio
Simplify the whole thing by introducing an enum em28xx_int_audio_type
which describes the internal audio type (none, ac97, i2s) and is hooked
directly to the device struct. Then get rid of field has_audio in struct
em28xx_audio_mode.
A follow-up patch will then remove struct em28xx_ac97_mode and finally
the whole struct em28xx_audio_mode.

types could be provided by devices at the same time, the current code is
totally broken for that case.
So clean up and simplify the usb audio class handling by replacing

interface) and "has_alsa_audio" (device has vendor audio interface) in
struct em28xx with a single enum em28xx_usb_audio_type.

[media] em28xx: check if a device has audio earlier
Better to split chipset detection from the audio setup. So, move the
detection code to em28xx_init_dev().
It broke analog audio of the Hauppauge winTV HVR 900 and very likely many other
em28xx devices.
Background:
The local variable has_audio in em28xx_usb_probe() describes if the currently
probed _usb_interface_ has an audio endpoint, while dev->audio_mode.has_audio
means that the _device_ as a whole provides analog audio.
Hence it is wrong to set dev->audio_mode.has_audio = has_audio in em28xx_usb_probe().
As result, audio support is no longer detected and configured on devices which
have the audio endpoint on a separate interface, because em28xx_audio_setup()
bails out immediately at the beginning.
Revert the faulty commit to restore the old audio detection procedure, which checks
the chip configuration register to determine if the device has analog audio.

Instead of using a temporary stack allocated i2c_client in em28xx_i2c_ir_handle_key(),
allocate/free the i2c_client at module init/uninit and hook it into struct em28xx_IR
(if the device has an i2c IR decoder).
This reduces the frame size of function em28xx_i2c_ir_handle_key() and speeds

While v4l2->users is the number of users of the whole device (all device nodes),

As a result. if one device node is open and a second device node is opened
(closed), the device is reinitialized (streaming is stopped).

When both VBI and video are streaming, and video stream is stopped,
a subsequent trial to restart it will fail, because S_FMT will

That prevents applications like zvbi to work properly.
Please notice that, while this fix it fully for zvbi, the

The uvcvideo webcam driver exposes the v4l2 control "Exposure (Absolute)"
which allows the user to control the exposure time of the webcam,
essentially controlling the brightness of the received image. By default
the webcam automatically adjusts the exposure time automatically but the
if you set the control "Exposure, Auto"="Manual Mode" the user can fix
the exposure time.
Unfortunately it seems that the Logitech C920 has a firmware bug where
it will forget that it's in manual mode temporarily during initialisation.
This means that the camera doesn't respect the exposure time that the user
requested if they request it before starting to stream video. They end up
with a video stream which is either too bright or too dark and must reset
the controls after video starts streaming.
This patch introduces the quirk UVC_QUIRK_RESTORE_CTRLS_ON_INIT which
causes the cached controls to be re-uploaded to the camera immediately
after initialising the camera. This quirk is applied to the C920 to work
around this camera bug.

TechnoTrend TT-connect CT2-4650 CI (0b48:3012) is an USB DVB-T2/C tuner with
the following components:
USB interface: Cypress CY7C68013A-56LTXC
Demodulator: Silicon Labs Si2168-A20
Tuner: Silicon Labs Si2158-A20
CI chip: CIMaX SP2HF
The firmware for the tuner is the same as for TechnoTrend TT-TVStick CT2-4400.
See https://www.mail-archive.com/linux-media@vger.kernel.org/msg76944.html
The demodulator needs a firmware that can be extracted from the Windows drivers.
File ttConnect4650_64.sys should be extracted from
http://www.tt-downloads.de/bda-treiber_4.1.0.4.zip (MD5 sum below).
3464bfc37a47b4032568718bacba23fb ttConnect4650_64.sys
Then the firmware can be extracted:
dd if=ttConnect4650_64.sys ibs=1 skip=273376 count=6424 of=dvb-demod-si2168-a20-01.fw
The SP2 CI module requires a definition of a function cxusb_tt_ct2_4650_ci_ctrl
that is passed on to the SP2 driver and called back for CAM operations.

Normally, ADAP_STREAMING bit is set in dvb_usb_start_feed and cleared in
dvb_usb_stop_feed.
But in exceptional cases, for example, when the tv is playing programs
and the tuner is pulled out, then dvb_usbv2_disconnect is called.
In such case, it will first call dvb_usbv2_adapter_frontend_exit to stop
dvb_frontend_thread, and then call dvb_usbv2_adapter_dvb_exit to clear
ADAP_STREAMING bit.
At this point, if dvb_frontend_thread is sleeping and waiting for
ADAP_STREAMING to be cleared to get out of sleep. then
dvb_frontend_thread can never be stoped, because clearing ADAP_STREAMING
bit is performed after dvb_frontend_thread is stopped (i.e. performed in
dvb_usbv2_adapter_dvb_exit).

When a new video frame is started, the driver takes the next video buffer from
the list of active buffers and moves it to dev->usb_ctl.vid_buf / dev->usb_ctl.vbi_buf
for further processing.
On streaming stop we currently only give back the pending buffers from the list
but not the ones which are currently processed.

When DVB is streaming and suspend is called, it will call
au0828_stop_transport(), with will clean the streaming flag.
Due to that, stop_urb_transfer() will be called twice,
causing an oops.
So, we need another flag to be used at resume, telling it
to restart DVB.
While here, add a logic at stop_urb_transfer() to prevent
it of being called twice, and convert the usb_streaming
flag into boolean.

dev->dvb is always not null, as it is an area at the dev
memory. So, checking if (dev->dvb) is always true.
Instead of this stupid check, what the code wants to do is
to know if the DVB was successully registered.
Fix it by checking, instead, for dvb->frontend. It should
also be sure that this var will be NULL if the device was

When the DVB code sets the frontend, it disables the IR
INT, probably due to some hardware bug, as there's no code
there at au8522 frontend that writes on register 0xe0.
Fixing it at au8522 code is hard, as it doesn't know if the
IR is enabled or disabled, and just restoring the value of
register 0xe0 could cause other nasty effects. So, better
to add a hack at au0828-input polling interval to enable int,

Commits 21dc61d3c0 and 7a1dd50b89 reduced the board I2C

while xc5000 uses i2c stretch when a command is sent to it,
au0828 doesn't support this feature.
However, this is needed only for Xceive tuners. The other
I2C devices can work at the max speed.
So, revert the workarounds at board level, handling it at
I2C level, only when talking with xc5000.

The basic API of rc-core used to be:
dev = rc_allocate_device();
dev->x = a;
dev->y = b;
dev->z = c;
rc_register_device();
which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:
dev = rc_allocate_device();
dev->x = a;
rc_set_allowed_protocols(dev, RC_BIT_X);
dev->z = c;
rc_register_device();
There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there

the RC RX packet is defined as:

u8 not_data;
The NEC protocol transmits in the order:
system
not_system
data
not_data
Note that the code defines the NEC extended scancode as:
scancode = be16_to_cpu(poll_reply->system16) << 8 | poll_reply->data;
i.e.
scancode = poll_reply->not_system << 16 |
poll_reply->system << 8 |
poll_reply->data;
Which, if the order *is* reversed, would mean that the scancode that
gets defined is in reality:
scancode = poll_reply->system << 16 |
poll_reply->not_system << 8 |
poll_reply->data;
Which is the same as the order used in drivers/media/rc/ir-nec-decoder.c.

The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.
To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.
The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.
To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

Commit 0ba2aeb6da increased the internal control ranges
to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value
control values in a division or modulus operations since not all architectures support
those natively.
Luckily, in almost all cases it is possible to just cast to 32 bits (the control value
is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to
use do_div in one function.

The current "wait_on_bit" interface requires an 'action'
function to be provided which does the actual waiting.
There are over 20 such functions, many of them identical.
Most cases can be satisfied by one of just two functions, one
which uses io_schedule() and one which just uses schedule().
So:
Rename wait_on_bit and wait_on_bit_lock to
wait_on_bit_action and wait_on_bit_lock_action
to make it explicit that they need an action function.
Introduce new wait_on_bit{,_lock} and wait_on_bit{,_lock}_io
which are *not* given an action function but implicitly use
a standard one.
The decision to error-out if a signal is pending is now made
based on the 'mode' argument rather than being encoded in the action
function.
All instances of the old wait_on_bit and wait_on_bit_lock which
can use the new version have been changed accordingly and their
action functions have been discarded.
wait_on_bit{_lock} does not return any specific error code in the
event of a signal so the caller must check for non-zero and
interpolate their own error code as appropriate.
The wait_on_bit() call in __fscache_wait_on_invalidate() was
ambiguous as it specified TASK_UNINTERRUPTIBLE but used
fscache_wait_bit_interruptible as an action function.
David Howells confirms this should be uniformly
"uninterruptible"
The main remaining user of wait_on_bit{,_lock}_action is NFS
which needs to use a freezer-aware schedule() call.
A comment in fs/gfs2/glock.c notes that having multiple 'action'
functions is useful as they display differently in the 'wchan'
field of 'ps'. (and /proc/$PID/wchan).
As the new bit_wait{,_io} functions are tagged "__sched", they
will not show up at all, but something higher in the stack. So
the distinction will still be visible, only with different
function names (gds2_glock_wait versus gfs2_glock_dq_wait in the
gfs2/glock.c case).
Since first version of this patch (against 3.15) two new action
functions appeared, on in NFS and one in CIFS. CIFS also now
uses an action function that makes the same freezer aware
schedule call as NFS.

When the audio encoding is changed the driver calls hdpvr_set_audio
with the current opt->audio_input value. However, that should have
been opt->audio_input + 1. So changing the audio encoding inadvertently
changes the input as well. This bug has always been there.
The second bug was introduced in kernel 3.10 and that broke the
default_audio_input module option handling: the audio encoding was
never switched to AC3 if default_audio_input was set to 2 (SPDIF input).
In addition, since starting with 3.10 the audio encoding is always set
at the start the first bug now always happens when the driver is loaded.
In the past this bug would only surface if the user would change the
audio encoding after the driver was loaded.
Also fixes a small trivial typo (bufffer -> buffer).

Currently gspca selects the first ISOC input endpoint as the input
transfer endpoint, however some devices can provide streams on endpoints
different then the first one, so some subdrivers (e.g. gspca_kinect) may
want to select a specific endpoint to use as a transfer endpoint.
Add an xfer_ep field to struct gspca_dev, and change alt_xfer() so that
it accepts a parameter which represents a specific endpoint address to
look for.
If a subdriver wants to specify a value for gspca_dev->xfer_ep it can do
that in its sd_config() callback.

It seems that there's a bug at au0828 hardware/firmware
related to alternate setting: when the device is already at
alt 5, a further call causes the URBs to receive -ESHUTDOWN.
I found two different encarnations of this issue:
1) at qv4l2, it fails the second time we try to open the
video screen;
2) at xawtv, when audio underrun occurs, with is very
frequent, at least on my test machine.
The fix is simple: just check if alt=5 before calling
set_usb_interface().

Well, what we call as "foo_attach" is the method that should
be called by the dvb_attach() macro.
It should be noticed that the name "dvb_attach" is really a
bad name and don't express what it does.
dvb_attach() basically does three things, if the frontend is
compiled as a module:
- It lookups for the module that it is known to have the
given symbol name and requests such module;
- It increments the module usage (anonymously - so lsmod
doesn't print who loaded the module);
- after loading the module, it runs the function associated
with the dynamic symbol.
When compiled as builtin, it just calls the function given to it.
As dvb_attach() increments refcount, it can't be (easily)
called more than once for the same module, or the kernel
will deny to remove the module, because refcount will never
be zeroed.
In other words, the function name given to dvb_attach()
should be one single symbol that will always be called
before any other function on that module to be used.
For almost all DVB frontends, there's just one function,
but, on dib8000, there are several exported symbols.
We need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.
So, let's rename this function, in order to prepare for
a next patch that will add a new attach() function that
will be the only one exported by this module.

As we need to get rid of all those direct calls, because they

lock as there is a longer wait for lock to appear in ibuf[6].
Remove last_key and key_timeout and use jiffies plus 60ms
to detect that streaming is still active.
If the current jiffies is time_after the interrupt urb overdue and

As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.
I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.
Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.
There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.
One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.
This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.
A complete fix, however, would also need to check the PM
conditions for the tuner and demux.

Currently stk1160_read_reg() uses a stack-allocated char to get the
read control value. This is wrong because usb_control_msg() requires
a kmalloc-ed buffer.
This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive
the read value.
While here, let's remove the urb_buf array which was meant for a similar
purpose, but never really used.

The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.
The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.
The pwc amd sdr-msi3101 drivers both had this construction:
if (mutex_lock_interruptible(&s->v4l2_lock))
return -ERESTARTSYS;
This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

Exporting functions for hardware filter is a bad idea, as it
breaks compilation if:
CONFIG_DVB_USB_AF9035=y
CONFIG_DVB_AF9033=m
Because the PID filter function calls would be hardcoded at
af9035.
The same doesn't happen with af9033_attach() because the
dvb_attach() doesn't hardcode it. Instead, it dynamically
links it at runtime.
However, calling dvb_attach() multiple times is problematic,
as it increments module kref.
So, the better is to pass one parameter for the af9033 module
to fill the hardware filters, and then use it inside af9035.

If a queue was canceled, then the buf_finish op was never called for the
pending buffers. So add this call to queue_cancel. Before calling buf_finish
set the buffer state to PREPARED, which is the correct state. That way the
states DONE and ERROR will only be seen in buf_finish if streaming is in
progress.
Since buf_finish can now be called from non-streaming state we need to
adapt the handful of drivers that actually need to know this.

The UVC specification uses alternate setting selection to notify devices
of stream start/stop. This breaks when using bulk-based devices, as the
video streaming interface has a single alternate setting in that case,
making video stream start and video stream stop events to appear
identical to the device. Bulk-based devices are thus not well supported
by UVC.
The webcam built in the Asus Zenbook UX302LA ignores the set interface
request and will keep the video stream enabled when the driver tries to
stop it. If USB autosuspend is enabled the device will then be suspended
and will crash, requiring a cold reboot.
USB trace capture showed that Windows sends a CLEAR_FEATURE(HALT)
request to the bulk endpoint when stopping the stream instead of
selecting alternate setting 0. The camera then behaves correctly, and
thus seems to require that behaviour.
Replace selection of alternate setting 0 with clearing of the endpoint
halt feature at video stream stop for bulk-based devices. Let's refrain
from blaming Microsoft this time, as it's not clear whether this
Windows-specific but USB-compliant behaviour was specifically developed
to handle bulkd-based UVC devices, or if the camera just took advantage
of it.

Implement em28xx_usb_driver suspend, resume, and reset_resume hooks.
These hooks will invoke em28xx core em28xx_suspend_extension() and
em28xx_resume_extension() to suspend and resume registered extensions.
Approach:
Add power management support to em28xx usb driver. This driver works in
conjunction with extensions for each of the functions on the USB device
for video/audio/dvb/remote functionality that is present on media USB
devices it supports. During suspend and resume each of these extensions
will have to do their part in suspending the components they control.
Adding suspend and resume hooks to the existing struct em28xx_ops will
enable the extensions the ability to implement suspend and resume hooks
to be called from em28xx driver. The overall approach is as follows:
-- add suspend and resume hooks to em28xx_ops
-- add suspend and resume routines to em28xx-core to invoke suspend
and resume hooks for all registered extensions.
-- change em28xx dvb, audio, input, and video extensions to implement
em28xx_ops: suspend and resume hooks. These hooks do what is necessary
to suspend and resume the devices they control.

Restructure the way we bring the various GPIOs out of reset. In particular:
1. we only need to setup the GPIOs as outputs once
2. there's no point in writing 0x40 to register 0x00 since that's the EEPROM
write protect and already it's configured as an input
3. Separate out the act of enabling the power supply and bringing the tuner
and demod out of reset. If you don't then the chip may not be properly
enabled (as the power supply is still ramping up when the chip comes
out of reset). This can result in probing failures.

mxl111sf_read_reg takes an address of a variable to write to as an argument.
drivers/media/usb/dvb-usb-v2/mxl111sf-gpio.c:mxl111sf_config_pin_mux_modes
passes several uninitialized stack variables to this routine, expecting
them to be filled in. In the event that something unexpected happens when
reading from the chip, we end up doing a pr_debug of the value passed in,
revealing whatever garbage happened to be on the stack.
Change the pr_debug to match what happens in the 'success' case, where we
assign buf[1] to *data.

Previously, we've been assuming that the video endpoints are always at usb
interface 0. Hence, if vendor audio endpoints are provided at a separate
interface, they were supposed to be at interface number > 0.
Instead of checking for (interface number > 0) to determine if an interface
is a pure audio interface, dev->is_audio_only should be checked.

The current code assumes that the analog + digital video endpoints are always at
interface number 0 when changing the alternate setting.
This seems to work fine for most existing devices.
However, at least the SpeedLink VAD Laplace webcam has the video endpoint on
interface number 3 (which fortunately doesn't cause any trouble because ist uses
bulk transfers only).
We already consider the actual interface number for audio endpoints, so
rename the the audio_ifnum variable and use it for all device types.
Also get get rid of a pointless (ifnum < 0) in em28xx-audio.

If something bad happens during init, we free the card data.
However, we still keep it initialized, causing some dependent
code to be called at .fini.
Fix it.

The option to load firmware asynchronously were added due to
a requirement with a few versions of udev. It turns that this was
a bad idea and caused regressions on drxk-based devices.
So, we end by only letting the firmware to be loaded syncronously
everywhere.
So, let's remove the bad code.
This patch partially reverts the changeset 8e30783b0b.

While the current hardcoded period is ok for the current values,
we may latter change the driver to work with different bit rates
or with different latencies than 64ms.

When the usb device is disconnected, the resources are no longer available,
so there is no reason to keep them registered.

v4l2_ctrl_handler_free() and v4l2_device_unregister() are currently only called
when the last user closes the device and the device is already disconnected.
But that's wrong, we need to call these functions whenever the em28xx-v4l
extension is closed and we can already do this if the device is still opened
by some users.
