[PATCH 0/2] iio: accel: kxsd9: fix use-after-free and PM leaks

[Biren Pandya <birenpandya@gmail.com>]

This series fixes a use-after-free during device removal and resolves 
multiple runtime PM reference leaks.

Changes in v3:
- Split the fixes into two patches (UAF fix and PM leaks fix) as 
  requested by Jonathan Cameron.
- remove(): Dropped the early return on PM resume failure. The driver now 
  makes a best-effort attempt to power down the device unconditionally, 
  addressing feedback from Andy Shevchenko and Jonathan Cameron.
- read_raw(): Mirrored the -EINVAL reset fix from write_raw() to ensure 
  symmetric error handling on invalid masks.
- Dropped redundant pm_runtime_mark_last_busy() calls, relying instead
  on pm_runtime_put_autosuspend().
