[PATCH v5 00/10] iio: adc: ti-ads1015: modernize resource management and bitfield logic

[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 unneeded '< 0' error checks for functions returning 0 or error.
- Converts mutex initialization to devm_mutex_init().
- Transitions runtime PM setup to devm_pm_runtime_set_active_enabled().
- Inlines the redundant ads1015_set_conv_mode() helper.
- Replaces custom shift macros with FIELD_PREP()/FIELD_GET().

v5:
- Reordered patches: inlined ads1015_set_conv_mode() before applying
  FIELD_PREP() to completely eliminate code churn.
- Extracted FIELD_PREP() evaluations into local variables for
  regmap_update_bits() calls to ensure clean line lengths and readability.
- Added a patch to return -ENODATA when i2c_get_match_data() fails, as
  requested by Andy Shevchenko.
- Split devm_mutex_init() into its own patch to decouple it from the
  runtime PM modernization, as requested by Andy Shevchenko.
