The variable ret is being assigned a return value and non-zero error
return paths are taken at all stages. At the end of the function ret
is always zero, so the ternary operator checking for zero ret is
redundant and can be replaced with just len instead.

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace
the array sentinel in all IIO drivers to the same style.
For some time, we've been trying to consistently use `{ }` (no trailing
comma, no comment, one space between braces) for array sentinels in the
IIO subsystem. Still nearly 50% of existing code uses a different style.
To save reviewers from having to request this trivial change as
frequently, let's normalize the style in all existing IIO drivers.
At least when code is copy/pasted to new drivers, the style will be
consistent.

Particularly great to see a resolver driver move out of staging via a
massive set of changes. Only took 13 years :)
One small patch added then reverted due to a report of test breakage
(ashai-kasei,ak8975: Drop deprecated enums.)
An immutable branch was used for some hid-senors changes in case
there was a need to take them into the HID tree as well.
New device support
-----------------
adi,hmc425a
- Add support for HMC540SLP3E broadband 4-bit digital attenuator.
kionix,kx022a
- Add support for the kx132-1211 accelerometer. Require significant
driver rework to enable this including add a chip type specific
structure to deal with the chip differences.
- Add support for the kx132acr-lbz accelerometer (subset of the kx022a
feature set).
lltc,ltc2309
- New driver for this 8 channel ADC.
microchip,mcp3911
- Add support for rest of mcp391x family of ADCs (there are various
differences beyond simple channel count variation.
Series includes some general driver cleanup.
microchip,mcp3564
- New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564
and their R variants of 16/24bit ADCs. A few minor fixed followed.
rohm,bu1390
- New driver for this pressure sensor.
Staging graduation
------------------
adi,ad1210 (after 13 or so years :)
- More or less a complete (step-wise) rewrite of this resolver driver
to bring it up to date with modern IIO standards. The fault signal
handling mapping to event channels was particularly complex and
significant part of the changes.
Features
--------
iio-core
- Add chromacity and color temperature channel types.
adi,ad7192
- Oversampling ratio control (called fast settling in datasheet).
adi,adis16475
- Add core support and then driver support for delta angle and delta
velocity channels. These are intended for summation to establish
angle and velocity changes over larger timescales. Fix was
needed for alignment after the temperature channel. Further fix
reduced set of devices for which the buffer support was applicable
as seems burst reads don't cover these on all devices.
hid-sensors-als
- Chromacity and color temperatures support including in amd sfh.
stx104
- Add support for counter subsystem to this multipurpose device.
ti,twl6030
- Add missing device tree binding description.
Clean up and minor fixes.
------------------------
treewide
- Drop some unused declarations across IIO.
- Make more use of device_get_match_data() instead of OF specific
approaches.
Similar cleanup to sets of drivers.
- Stop platform remove callbacks returning anything by using the
temporary remove_new() callback.
- Use i2c_get_match_data() to cope nicely with all types of ID table
entry.
- Use device_get_match_data() for various platform device to cope
with more types of firmware.
- Convert from enum to pointer in ID tables allowing use of
i2c_get_match_data().
- Fix sorting on some ID tables.
- Include specific string helper headers rather than simply string_helpers.h
docs
- Better description of the ordering requirements etc for
available_scan_masks.
tools
- Handle alignment of mixed sizes where the last element isn't the biggest
correctly. Seems that doesn't happen often!
adi,ad2s1210
- Lots of work from David Lechner on this driver including a few fixes
that are going with the rework to avoid slowing that down.
adi,ad4310
- Replace deprecated devm_clk_register()
adi,ad74413r
- Bring the channel function setting inline with the datasheet.
adi,ad7192
- Change to FIELD_PREP(), FIELD_GET().
- Calculate f_order from the sinc filter and chop filter states.
- Move more per chip config into data in struct ad7192_chip_info
- Cleanup unused parameter in channel macros.
adi,adf4350
- Make use of devm_* to simplify error handling for many of the setup
calls in probe() / tear down in remove() and error paths. Some more
work to be done on this one.
- Use dev_err_probe() for errors in probe() callback.
adi,adf4413
- Typo in function name prefix.
adi,adxl345
- Add channel scale to the chip type specific structure and drop
using a type field previously used for indirection.
asahi,ak8985
- Fix a mismatch introduced when switching from enum->pointers
in the match tables.
amlogic,meson
- Expand error logging during probe.
invensense,mpu6050
- Support level-shifter control. Whilst no one is sure exactly what this
is doing it is needed for some old boards.
- Document mount-matrix dt-binding.
mediatek,mt6577
- Use devm_clk_get_enabled() to replace open coded version and move
everything over to being device managed. Drop now empty remove()
callback. Fix follows to put the drvdata back.
- Use dev_err_probe() for error reporting in probe() callback.
memsic,mxc4005
- Add of_match_table.
microchip,mcp4725
- Move various chip specific data from being looked up by chip ID to
data in the chip type specific structure.
silicon-labs,si7005
- Add of_match_table and entry in trivial-devices.yaml
st,lsm6dsx
- Add missing mount-matrix dt binding documentation.
st,spear
- Use devm_clk_get_enabled() and some other devm calls to move everything
over to being device managed. Drop now empty remove() callback.
- Use dev_err_probe() to better handled deferred probing and tidy up
error reporting in probe() callback.
st,stm32-adc
- Add a bit of additional checking in probe() to protect against a NULL
pointer (no known path to trigger it today).
- Replace deprecated strncpy()
ti,ads1015

The devm_clk_get_enabled() helper:
- calls devm_clk_get()
- calls clk_prepare_enable() and registers what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
Also replace devm_regulator_get() and regulator_enable() with
devm_regulator_get_enable() helper and remove regulator_disable().
Replace iio_device_register() with devm_iio_device_register() and remove
iio_device_unregister().
And st->reg is not used anymore, so remove it.
As Jonathan pointed out, couple of things that are wrong:
1) The device is powered down 'before' we unregister it with the
subsystem and as such userspace interfaces are still exposed which
probably won't do the right thing if the chip is powered down.
2) This isn't done in the error paths in probe.
To solve this problem, register a new callback adf4350_power_down()
with devm_add_action_or_reset(), to enable software power down in both
error and device detach path. So the remove function can be removed.
Remove spi_set_drvdata() from the probe function, since spi_get_drvdata()
is not used anymore.

The regulator_get_voltage() function returns negative error codes.
This function saves it to an unsigned int and then does some range
checking and, since the error code falls outside the correct range,
it returns -EINVAL.
Beyond the messiness, this is bad because the regulator_get_voltage()
function can return -EPROBE_DEFER and it's important to propagate that
back properly so it can be handled.

This driver only turns the power on at probe and off via a custom
devm_add_action_or_reset() callback. The new devm_regulator_get_enable()
replaces this boilerplate code.
Note that in event of an error on the devm_regulator_get() the driver
would have continued without enabling the regulator which is probably
not a good idea. So here we handle any error as a reason to fail the
probe(). In theory this may expose breakage on a platform that was
previously papered over but it seems low risk.

Several on-running cleanup efforts dominate this time, plus the DMA
safety alignment issue identified due to improved understanding of
the restrictions as a result of Catalin Marinas' efforts in that area.
One immutable branch in here due to MFD and SPMI elements needed for
the qcom-rradc driver.
Device support
* bmi088
- Add support for bmi085 (accelerometer part of IMU)
- Add support for bmi090l (accelerometer part of IMU)

multiple device types and cleanup noticed whilst working on driver.

worked for a long time by coincidence, but correct alignment is
ARCH_KMALLOC_MINALIGN. As there is activity around this area, introduce
an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather
than every driver in future. Note, there have been no reports of this
bug in the wild, and it may not happen on any platforms supported by
upstream, so no rush to backport these fixes.

Merge tag 'iio-fixes-for-5.19a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next
Jonathan writes:
1st set of IIO fixes for the 5.19 cycle.
Most of these have been in next for a long time. Unfortunately there
was one stray patch in the branch (wasn't a fix), so I've just rebased
to remove that.
* testing
- Fix a missing MODULE_LICENSE() warning by restricting possible build
configs.
* Various drivers
- Fix ordering of iio_get_trigger() being called before
iio_trigger_register()
* adi,admv1014
- Fix dubious x & !y warning.
* adi,axi-adc
- Fix missing of_node_put() in error and normal paths.
* aspeed,adc
- Add missing of_node_put()
* fsl,mma8452
- Fix broken probing from device tree.
- Drop check on return value of i2c write to device to cause reset as
ACK will be missing (device reset before sending it).
* fsl,vf610
- Fix documentation of in_conversion_mode ABI.
* iio-trig-sysfs
- Ensure irq work has finished before freeing the trigger.
* invensense,mpu3050
- Disable regulators in error path.
* invensense,icm42600
- Fix collision of enum value of 0 with error path where 0 is no match.
* renesas,rzg2l_Adc
- Add missing fwnode_handle_put() in error path.
* rescale
- Fix a boolean logic bug for detection of raw + scale affecting an
obscure corner case.
* semtech,sx9324
- Check return value of read of pin_defs
* st,stm32-adc:
- Fix interaction across ADC instances for some supported devices.
- Drop false spurious IRQ messages.
- Fix calibration value handling. If we can't calibrate don't expose the
vref_int channel.
- Fix maximum clock rate for stm32pm15x
* ti,ads131e08
- Add missing fwnode_handle_put() in error paths.
* xilinx,ams
- Fix variable checked for error from platform_get_irq()
* x-powers,axp288
- Overide TS_PIN bias current for boards where it is not correctly
initialized.
* yamaha,yas530
- Fix inverted check on calibration data being all zeros.
* tag 'iio-fixes-for-5.19a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (26 commits)
iio:proximity:sx9324: Check ret value of device_property_read_u32_array()

iio: adc: rzg2l_adc: add missing fwnode_handle_put() in rzg2l_adc_parse_properties()
iio: trigger: sysfs: fix use-after-free on remove
...
The warning comes from __BF_FIELD_CHECK()
specifically
BUILD_BUG_ON_MSG(__builtin_constant_p(_val) ? \
~((_mask) >> __bf_shf(_mask)) & (_val) : 0, \
_pfx "value too large for the field"); \
The code was using !(enum value) which is not particularly easy to follow
so replace that with explicit matching and use of ? 0 : 1; or ? 1 : 0;
to improve readability.

strtobool() is deprecated and just a wrapper around kstrtobool().Replace
it with kstrtobool() so the deprecated function can be removed eventually.

Here is the big set of char/misc and other small driver subsystem
updates for 5.18-rc1.
Included in here are merges from driver subsystems which contain:
- iio driver updates and new drivers
- fsi driver updates
- fpga driver updates
- habanalabs driver updates and support for new hardware
- soundwire driver updates and new drivers
- phy driver updates and new drivers
- coresight driver updates
- icc driver updates
Individual changes include:
- mei driver updates
- interconnect driver updates
- new PECI driver subsystem added
- vmci driver updates
- lots of tiny misc/char driver updates
There will be two merge conflicts with your tree, one in MAINTAINERS
which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
which also should be easy to resolve.
All of these have been in linux-next for a while with no reported
problems.
