[PATCH v3 0/6] iio: magnetometer: ak8975: modernize and cleanup driver

[Joshua Crofts]

This series modernizes and cleans up the ak8975 driver, migrating to
more modern kernel APIs and cleaning up legacy code.

Changes include:
 - replacing usleep_range() with fsleep() for optimization
 - migrating to iopoll macros for better device polling
 - removing unused headers and adding new ones
 - checkpatch.pl fixes

v2:
 - PATCH 1: reverted alphabetical header ordering per logical change
   separation
 - PATCH 2: added newline between fsleep() and return
 - PATCH 3: fixed open parenthesis formatting
 - PATCH 4: fixed whitespace issues, added <linux/time.h> for
   USEC_PER_MSEC macro
v3:
 - PATCH 1 & 2: split alphabetical ordering and header removal into two
   separate patches
 - PATCH 4: commit message fix
 - PATCH 5 & 6: split error handling and polling loop replacement into
   two separate patches
