  iio: chemical: atlas-sensor: use iio_trigger_poll_nested() to fix remove UAF (2026-08-07 23:51:05 +0100)

----------------------------------------------------------------
IIO: 2nd set of fixes for the 7.2 cycle.

Given timing these are probably now merge window material.

Usual mixed bunch of ancient issues and newer ones.

core,buffer
- Fix a potential UAF in release on anonymous buffers.
- Make sure DMA fence lock lifetime matches that of the DMA fence.
- Make IIO DMA fence release RCU safe.
various
- Kconfig missing REGMAP* related selects.
- Unbalance of runtime pm or regulators in error paths.

adi,ad3552r-hs
- Fixing wrong buffers size for string printing.
adi,ad4080
- Fix 16-bit part support by adding path to tell the backend what
  the data size is - avoiding corrupted data capture.
adi,ad5446
- Wrong MODULE_DEVICE_TABLE() type due to case error.
atlas,sensor
- Drop use of irq_work() in favour of iio_trigger_poll_nested() avoiding
  a possible UAF.
hid-temperature
- Potential release ordering issue due to mixed devm and not that
  can lead to long timeouts.
infineon,dps310
- Fix NULL dereference on ACPI platforms.
invense,mpu3050
- Fix sign of raw angular velocity readings.
mitsubishi,m62332
- Fix a regulator reference counting issue when switching channels.
sharp,gp2ap002
- Unbalanced runtime PM on repeated event writes.
- Reenable irq if runtime suspend fails.
ti,ads7138
- Disable statistics gathering whilst reading conversions results
  to avoid data corruption.
ti,opt4001
- Ensure integration times with integer part are rejected rather than
  ignoring the integer part of the value.
- Fix use of wrong register.
- Pointer type mismatch to div_u64_rem()
- Fix reversed GENMASK() arguements.
ti,opt4060
- Ensure integration times with integer part are rejected rather than
  ignoring the integer part of the value.
- Pointer type mismatch to div_u64_rem()
- Wrong register name in an error print.
ti,pac1921
- Fix wrong channel used in the trigger handler for some combinations
  of enabled channels.
