Subject: [PATCH v2 0/8] Support ROHM KX134ACR-LBZ

This patch series introduces support for ROHM KX134ACR-LBZ and
KX134-1211 accelerometers.

The KX134ACR-LBZ is almost identical to the KX132ACR-LBZ. Similarly the
KX134-1211 is almost identical to the KX132-1211. The differencies
visible to the driver are different g-ranges and the "Who am I"
-identification register's values.

This series does also convert parts of the GTS helpers and the kx022a
driver to use __cleanup - based scoped free/unlock operations, and fixes
the value of required wait time after sensor reset. The wait time value
fixup is cosmetic/documentational, as the time that has been slept has
likely been larger than required due to the msleep() implementation.

Revision history:
v1 => v2:
 - Rebased on iio-fixes to avoid conflicts with queued fixes.
 - Added the reset delay change to the series to avoid conflicts. Was
   previously sent as an individual patch:
   https://lore.kernel.org/all/ZzWfXbjaDkFnu_Jg@mva-rohm/
 - Added support for kx134-1211

The v1 can be found from:
https://lore.kernel.org/all/cover.1731495937.git.mazziesaccount@gmail.com/

The patch 1/8 is the delay fixup mentioned above.

The patch 2/8 contains GTS helper change, which is independent from the
rest of the series. It can be applied/rejected independently.

Patch 3/8 changes kx022a to use scoped mutexes. It can also be applied
as an independent improvement even if the kx134acr-lbz support was not
added.

Patch 4/8 adds mechanisms for supporting sensors with different
g-ranges in the kx022a driver.

5-8/8 add support for new hardware, kx134acr-lbz and kx134-1211.
