[PATCH v2 0/5] Using dev_err_probe as it simplifies error handling and ensures consistent error reporting.

[PATCH v2 0/5] Using dev_err_probe as it simplifies error handling and ensures consistent error reporting.

[Prashant Rahul]

Errors are logged when enabling the regulator or adding the cleanup action
fails, but not when buffer setup fails. This adds that missing log.

changes in v2:
- ti-adc084s021: drop unnecessary braces around single statement if block

v1: https://lore.kernel.org/linux-iio/20260618231543.413771-1-prashantrahul23@gmail.com/
