[PATCH v5 0/2] iio: magnetometer: bmc150_magn: cleanup and formatting

[Neel Bullywon <neelb2403@gmail.com>]

This v5 series refactors the bmc150_magn driver to use automated cleanup
helpers for mutex operations and modernizes the delay function usage.

Changes in v5:
- Split into two patches as requested by maintainer:
  - Patch 1/2: All functional changes (guard/scoped_guard, fsleep)
  - Patch 2/2: Pure formatting/style cleanups
- Use scoped_guard() instead of { guard(); ... } for short scopes
- Left trigger_handler unchanged per maintainer feedback
- Use fsleep() instead of usleep_range() per maintainer feedback
- Dropped formatting changes that did not improve readability
- Added braces around guard() in case blocks for clear scope

Changes in v4:
- Replace scoped_guard() with guard() to avoid lexical scope issues with goto
  and return values which caused logic errors in previous versions.
- Replace msleep(5) with usleep_range(5000, 6000) to avoid checkpatch
  warning.
- Fix indentation and line wrapping to cleanliness.
- Extend guard() usage to all mutex_lock() instances in the driver.

Changes in v3:
- Add Reviewed-by tags.

Changes in v2:
- Use guard() for mutex protection in bmc150_magn_data_rdy_trigger_set_state.

[Patch 1/2] Converts manual mutex_lock/unlock patterns to guard() and
scoped_guard() helpers, and replaces msleep(5) with fsleep(5000).

[Patch 2/2] Adds spaces inside braces for initializer lists and fixes
scan_masks array indentation. No functional changes.
