[PATCH v5 0/4] iio: accel: mma8452: use modern coding style and resource cleanup

[Sanjay Chitroda via B4 Relay]

Hi all,

This series contains a nuber of small fixes, cleanup and improvements
for the mma8452 accelerometer driver.

The changes modernize macro like mutex with guard(), bulk regulator,
IIO_DEV_ACQUIRE_DIRECT_MODE() and etc.

Changes in v5:
- Drop the PM runtime handling patch, as suitable hardware is not
  available to properly validate the PM state transitions.
- Apply reviewed tags.
- Rebase series onto the latest iio/testing branch.
- Link to v4: https://patch.msgid.link/20260602-15-apr-pm-iio-mma8452-v4-temp-v4-0-26d6dff8fc55@xxxxxxxxx
Changes in v4:
- Part of the series already merged into the IIO tree; rebase the
  remaining patches onto the latest iio/testing branch.
- Link to v3: https://lore.kernel.org/all/20260602-15-apr-pm-iio-mma8452-v4-temp-v4-0-26d6dff8fc55@xxxxxxxxx
Changes in v3:
- Following input from Andy and Jonathan added new changes as following
  0001: handle return value to have proper error propagation
  0002: use non-devm API to maintain resource management LIFO order
  0006: convert individual regulator using bulk regulator API
  0009: use IIO cleanup helper for DIRECT_MODE
- Address kernel coding stype specific review comment
- Reorder local struct device and dev_err_probe change
v2 series -> https://lore.kernel.org/all/20260422165643.2148195-1-sanjayembedded@xxxxxxxxx/
Changes in v2:
- 0005: address review comment from Andy and Geert
  and use DEFINE_RUNTIME_DEV_PM_OPS macro
- Added new cleanup channges in mma8452 driver

No functional behavior changes are intended.

Testing:
  - Compiled with W=1
  - Build-tested on QEMU x86_64

Feedback and reviews are very welcome.
