[PATCH v7 0/3] iio: magnetometer: bmc150_magn: cleanup and formatting

[Neel Bullywon]

This series cleans up the bmc150_magn driver in three patches:

1/3: Replace manual mutex lock/unlock with guard()/scoped_guard()
2/3: Replace msleep(5) with fsleep(5 * USEC_PER_MSEC)
3/3: Minor formatting cleanup for initializer lists and indentation

Changes in v7:
- Place cleanup.h include just before delay.h (Andy).
- Use guard() with case-level braces instead of scoped_guard() for the
  IIO_CHAN_INFO_RAW case block in read_raw (Andy).
- Apply case-level braces consistently to all case blocks using guard()
  in write_raw (Andy).
- Use guard() instead of scoped_guard() for suspend, returning
  directly (David).
- Keep samp_freq_table as one entry per line with fixed indent and
  spaces inside braces (David, Andy).

Changes in v6:
- Split fsleep change into its own patch (Andy).
- Use scoped_guard() instead of { guard() } for the IIO_CHAN_INFO_RAW
  case block in read_raw (Andy).
- Use 5 * USEC_PER_MSEC instead of 5000 for fsleep (Andy).
- Restyle bmc150_magn_samp_freq_table to group four entries per line
  with index comments (Andy).
- Remove trailing comma from scan_masks terminator (Andy).

Changes in v5:
- Split into two patches: functional and formatting (Jonathan).
- Use fsleep() instead of usleep_range() (Jonathan).
- Use scoped_guard() for short single-statement scopes (Jonathan).
- Add {} scope for guard() in case blocks (Jonathan).
- Leave trigger_handler unchanged (Jonathan).
- Drop all unnecessary reformatting (Jonathan).

Changes in v4:
- Extend guard() usage to all mutex_lock() instances in the driver.
- Replace msleep(5) with usleep_range(5000, 6000).

Changes in v3:
- Add Reviewed-by tags.

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