[PATCH v3 0/3] iio: light: ltr501: cleanups and modernizations

[rafasales em usp.br]

From: "Rafael B. Sales" <rafasales em usp.br>

This series cleans up the iio/light/ltr501.c driver by sorting header
includes according to the IWYU principles and simplifying locking
using automatic cleanup helpers.

Also replaces instances of `scnprintf()` with `sysfs_emit_at()`, as
the latter is PAGE_SIZE-aware.

Changes in v3:
- Added patch to replace `scnprintf()` with `sysfs_emit_at()`
- PATCH 1: reformatted headers and minimized include redundancy,
removed cleanup.h header
- PATCH 2: replaced some `scoped_guard()` instances with
{} + `guard()`, included cleanup.h header

Changes in v2:
- Added patch to sort header includes
- Fixed naming scheme for functions in commit message
- Reverted original lock boundaries
- Simplified returns

Rafael B. Sales (3):
  iio: light: ltr501: update header inclusions
  iio: light: ltr501: use automatic cleanup of locks
  iio: light: ltr501: use `sysfs_emit_at()` for showing scales
