Subject: [PATCH v2] pwm: meson: Remove error print for devm_add_action_or_reset()
Date: Tue, 5 Aug 2025 11:33:36 +0200	[thread overview]
Message-ID: <pndwm7ikt8v.a.out@axis.com> (raw)

When `devm_add_action_or_reset()` fails, it is due to a failed memory
allocation and will thus return `-ENOMEM`. `dev_err_probe()` doesn't do
anything when error is `-ENOMEM`. Therefore, remove the useless call to
`dev_err_probe()` when `devm_add_action_or_reset()` fails, and just
return the value instead.

Changes in v2:

* Split the patch to one seperate patch for each sub-system.
