[PATCH v3 0/2] staging: iio: addac: adt7316: clean up header inclusions

[Abdelnasser Hussein]

This series cleans up header inclusions in adt7316.c by following
the Include What You Use (IWYU) principle.

The series is split into two logical steps:
1. Sort existing header inclusions alphabetically without modifying the
   list of included headers. Keep subsystem <linux/iio/*> headers
   separated and insert a blank line before "adt7316.h".
2. Drop proxy header <linux/kernel.h>, explicitly add missing headers
   (<linux/bits.h>, <linux/err.h>, <linux/errno.h>, <linux/kstrtox.h>,
   <linux/pm.h>, <linux/string.h>, <linux/types.h>), drop unused headers
   (<linux/i2c.h>, <linux/list.h>, <linux/rtc.h>, <linux/slab.h>,
   <linux/workqueue.h>), and maintain alphabetical sorting.

v3:
 - Split the series as suggested by Joshua Crofts: patch 1 only sorts
   the headers, patch 2 replaces kernel.h and adds/drops headers.
 - Explicitly include <linux/err.h>, <linux/errno.h>, and
   <linux/types.h> per IWYU following verification of symbols used.

v2:
 - Address review feedback from Andy Shevchenko: drop <linux/kernel.h>
   and include the headers actually used.
 - Split the original patch into a 2-patch series.

v1:
 - Initial submission.
