Hi all,

This series contains a small fixes, cleanup and improvements to use
modern kernel helper API and coding style for mma8452 accel driver.

The changes modernize mutex with guard(), dev_err_probe usage,
resolve checkpatch CHECKS and pm_ptr macro usage.

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@gmail.com/
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.

Thanks,
Sanjay Chitroda
