[PATCH v6 00/11] iio: adc: ti-ads1015: modernize resource management and driver setup

[Archit Anant <architanant5@gmail.com>]

This series modernizes the ti-ads1015 driver by updating its runtime PM
handling, error handling, resource management, and register bitfield
operations.

This series builds on top of Stepan Ionichev's devm error path fix [1] and:

- Replaces SET_RUNTIME_PM_OPS() with DEFINE_RUNTIME_DEV_PM_OPS().
- Sorts the driver headers alphabetically.
- Returns -ENODATA when match data is missing.
- Uses a local device pointer in probe.
- Converts suitable error paths to dev_err_probe().
- Drops unnecessary '< 0' error checks for functions returning 0 or an
error.
- Converts mutex initialization to devm_mutex_init().
- Transitions runtime PM setup to devm_pm_runtime_set_active_enabled().
- Removes the unnecessary ads1015_set_power_state() helper and uses
runtime PM helpers directly at the call sites.
- Inlines the redundant ads1015_set_conv_mode() helper.
- Replaces custom shift macros with FIELD_PREP()/FIELD_GET().
