[PATCH v4 00/36] HID: iio: basic clean up and introduce devm_ API for HID sensors

[Sanjay Chitroda]

From: Sanjay Chitroda <sanjayembeddedse@xxxxxxxxx>

Key highlights:
- 0000-0024: General cleanup and kernel few coding style fixes across HID IIO drivers
- 0025: Remove unused iio_dev argument from HID IIO sensor helper
- 0026: Introduce devm_hid_sensor_setup_trigger() device-managed API
- 0027-0036: Convert HID IIO sensor drivers to use the new devm-based trigger setup

changes in v4:
- Extend the series to cover remaining HID IIO drivers with devm API usage
- Reorder patches to place cleanup and warning fix at beginning and,
  devm-related changes toward the end based on feedback from David
- v3 series -> https://lore.kernel.org/all/20260509101040.791404-1-sanjayembedded@xxxxxxxxx/
changes in v3:
- Added cleanup and prepratory changes before adding devm_ API
  conversion based on self review: 0002, 0004, 0006, 0007 and 0008
- Address andy's review comment on commit message and coding style
- v2 series -> https://lore.kernel.org/all/20260429175918.2541914-1-sanjayembedded@xxxxxxxxx/
changes in v2:
- Following input from Jonathan and Andy, squash initial patch v1
  series in single change as individual change should not break anything
- Add devm API support and two driver using the same
- v1 series -> https://lore.kernel.org/all/20260428071613.1134053-1-sanjayembedded@xxxxxxxxx/

Testing:
  - Compiled with W=1 for each patch in series
  - Build-tested on QEMU x86_64

P.S.
- Sashiko reported an issue in a different driver and noted that it is not
  introduced by this series. I have taken this feedback into account and
  will address the actual issue in a separate series focus on that driver.
- Once this series is merged into the IIO tree, a number of HID IIO
  drivers will become available to fully converted to devm API usage.
- The changes are organized across drivers to keep similar modifications
  grouped together for consistency, making the series easier to review,
  rather than grouping all changes per driver.

Thanks,
Sanjay Chitroda
