[PATCH v4 0/8] iio: adc: ti-ads1015: modernize driver

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 the series [1] and:
- replaces SET_RUNTIME_PM_OPS() with DEFINE_RUNTIME_DEV_PM_OPS().
- sorts the driver headers.
- uses a local device pointer in probe.
- converts suitable error paths to dev_err_probe().
- drops unneeded < 0 error checks.
- converts mutex and runtime PM handling to managed resources.
- replaces custom shift macros with FIELD_PREP()/FIELD_GET().
- removes the redundant ads1015_set_conv_mode() helper.

v4:
- Rebased the series as requested by Jonathan Cameron.
- Use devm_pm_runtime_set_active_enabled() for runtime PM setup.
- Reworked the register bitfield changes and inlined
  ads1015_set_conv_mode() following review feedback.
- Incorporated review feedback from Jonathan Cameron and Andy Shevchenko.
