[PATCH v3 0/8] iio: adc: ti-ads1015: modernize resource management

[Archit Anant <architanant5@gmail.com>]

This series modernizes the ti-ads1015 by transitioning it
to a fully devm_ architecture.

By moving resource allocation, device registration, and runtime power
management to the devm_ infrastructure, the teardown sequence is now
guaranteed to execute safely in the reverse order of initialization.
This allows for the complete removal of the ads1015_remove() function,
eliminating boilerplate code and reducing the risk of future resource
leaks.

Also the driver's configuration logic has been updated to use
the modern FIELD_PREP() and FIELD_GET() macros, allowing the removal
of all custom _SHIFT macros and a redundant helper function.

Additionally, housekeeping patches are included to ensure header
includes remain alphabetically sorted, dev_err_probe() is used
consistently, and PM macros are updated to modern standards.

Changes in v3:
- Added Patch 7 to replace all custom _SHIFT macros with FIELD_PREP
  and FIELD_GET as requested by Jonathan Cameron.
- Added Patch 8 to inline ads1015_set_conv_mode() directly at call
  sites, allowing for the removal of the final _SHIFT macro.

Changes in v2:
- Split the monolithic v1 patch into a 6-patch series to isolate
  housekeeping, bug fixes, and API modernizations for easier review
  and backporting.
- Patch 1: Added to modernize PM ops and remove #ifdef CONFIG_PM.
- Patch 2: Added to fix a pre-existing PM leak on probe failure
  identified by Jonathan Cameron.
- Patch 3: Extracted header sorting into a prerequisite patch.
- Patch 4 & 5: Extracted the introduction of the local 'dev' pointer
  and dev_err_probe() conversions, suggested by Jonathan Cameron.
- Patch 6: Now contains only the devm_ conversions and the removal
  of ads1015_remove().
