Upon resume from system suspend, the PM runtime core issues the
following warning:
tegra-xudc 3550000.usb: Runtime PM usage count underflow!
This is because tegra_xudc_resume() unconditionally calls
schedule_work(&xudc->usb_role_sw_work) whether or not anything has
changed, which causes tegra_xudc_device_mode_off() to be called
even when we're already in that mode.
Keep track of the current state of "device_mode", and only schedule
this work if it has changed from the hardware state on resume.

Here is the big set of USB and Thunderbolt driver changes for 6.17-rc1.
Lots of little things in here, mostly all small cleanups and updates, no
major new features this development cycle. Stuff included in here is:
- xhci minor tweaks for error handling
- typec minor updates and a driver update
- gadget driver api cleanups
- unused function removals
- unbind memory leak fixes
- a few new device ids added
- a few new devices supported for some drivers
- other minor cleanups and changes
All of these have been in linux-next with no reported issues, with the
leak fixes being in the shortest amount of time, but they are "obviously
correct" :)

These drivers have no way to probe as there are no match tables nor
devices created with a matching name in the kernel tree.
Marvell UDC was only ever supported by board files which were removed
in 2022.
For Marvell U3D, which was added in 2012, the PXA2128 aka MMP3 support
was never upstreamed with board files and only revived in 2019 with DT
support. No U3D DT support has been added since then.
The PLX net2272 driver was formerly used on blackfin. It also has PCI
support, but that appears to be only for a development board which is
likely unused given this device dates back to 2006.

from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.

The syzbot fuzzer has been encountering "task hung" problems ever
since the dummy-hcd driver was changed to use hrtimers instead of
regular timers. It turns out that the problems are caused by a subtle
difference between the timer_pending() and hrtimer_active() APIs.
The changeover blindly replaced the first by the second. However,
timer_pending() returns True when the timer is queued but not when its
callback is running, whereas hrtimer_active() returns True when the
hrtimer is queued _or_ its callback is running. This difference
occasionally caused dummy_urb_enqueue() to think that the callback
routine had not yet started when in fact it was almost finished. As a
result the hrtimer was not restarted, which made it impossible for the
driver to dequeue later the URB that was just enqueued. This caused
usb_kill_urb() to hang, and things got worse from there.
Since hrtimers have no API for telling when they are queued and the
callback isn't running, the driver must keep track of this for itself.
That's what this patch does, adding a new "timer_pending" flag and
setting or clearing it at the appropriate times.

Pull USB fixes from Greg KH:
"Here are some small USB fixes for some reported problems for 6.12-rc3.
Include in here is:
- fix for yurex driver that was caused in -rc1
- build error fix for usbg network filesystem code
- onboard_usb_dev build fix
- dwc3 driver fixes for reported errors
- gadget driver fix
- new USB storage driver quirk

All of these have been in linux-next for a while with no reported
issues"
* tag 'usb-6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
net/9p/usbg: Fix build error
USB: yurex: kill needless initialization in yurex_read
Revert "usb: yurex: Replace snprintf() with the safer scnprintf() variant"
usb: xhci: Fix problem with xhci resume from suspend
usb: misc: onboard_usb_dev: introduce new config symbol for usb5744 SMBus support
usb: dwc3: core: Stop processing of pending events if controller is halted
usb: dwc3: re-enable runtime PM after failed resume
usb: storage: ignore bogus device raised by JieLi BR21 USB sound chip
usb: gadget: core: force synchronous registration
Registering a gadget driver is expected to complete synchronously and
immediately after calling driver_register() this function checks that
the driver has bound so as to return an error.
Set PROBE_FORCE_SYNCHRONOUS to ensure this is the case even when
asynchronous probing is set as the default.

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/usb to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")
To quote that commit,
At -rc1 we'll need do a mechanical removal of no_llseek -
git grep -l -w no_llseek | grep -v porting.rst | while read i; do
sed -i '/\<no_llseek\>/d' $i
done
would do it.
Unfortunately, that hadn't been done. Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
.llseek = no_llseek,
so it's obviously safe.

Make sure the descriptor has been set before looking at maxpacket.
This fixes a null pointer panic in this case.
This may happen if the gadget doesn't properly set up the endpoint
for the current speed, or the gadget descriptors are malformed and
the descriptor for the speed/endpoint are not found.
No current gadget driver is known to have this problem, but this
may cause a hard-to-find bug during development of new gadgets.

Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Define PCIE_RESET_CONFIG_DEVICE_WAIT_MS for the generic 100ms
required after reset before config access (Kevin Xie)
- Define PCIE_T_RRS_READY_MS for the generic 100ms required after
reset before config access (probably should be unified with
PCIE_RESET_CONFIG_DEVICE_WAIT_MS) (Damien Le Moal)
Resource management:
- Rename find_resource() to find_resource_space() to be more
descriptive (Ilpo Järvinen)
- Export find_resource_space() for use by PCI core, which needs to
learn whether there is available space for a bridge window (Ilpo
Järvinen)
- Prevent double counting of resources so window size doesn't grow on
each remove/rescan cycle (Ilpo Järvinen)
- Relax bridge window sizing algorithm so a device doesn't break
simply because it was removed and rescanned (Ilpo Järvinen)
- Evaluate the ACPI PRESERVE_BOOT_CONFIG _DSM in
pci_register_host_bridge() (not acpi_pci_root_create()) so we can
unify it with similar DT functionality (Vidya Sagar)
- Extend use of DT "linux,pci-probe-only" property so it works
per-host bridge as well as globally (Vidya Sagar)
- Unify support for ACPI PRESERVE_BOOT_CONFIG _DSM and the DT
"linux,pci-probe-only" property in pci_preserve_config() (Vidya
Sagar)

prevents transactions between functions even though it doesn't
advertise ACS, so the functions can be attached individually via
VFIO (Ajit Khaparde)
Peer-to-peer DMA:
- Add a "pci=config_acs=" kernel command-line parameter to relax
default ACS settings to enable additional peer-to-peer
configurations. Requires expert knowledge of topology and ACS
