If an error occurs after a successful 'regulator_enable()' call,
'regulator_disable()' must be called.

Fix the error handling path of the probe accordingly.

The remove function doesn't need to be fixed, because the
'regulator_disable()' call is already hidden in 'dwc3_meson_g12a_suspend()'
which is called via 'pm_runtime_set_suspended()' in the remove function.

Please review carefully.

I'm not that sure about:
   The remove function doesn't need to be fixed, because the
   'regulator_disable()' call is already hidden in 'dwc3_meson_g12a_suspend()'
   which is called via 'pm_runtime_set_suspended()' in the remove function.

This is more a guess than anything else!

I am not 100% sure about the suspend code-path, so I am hoping that
someone else (for example Neil) can also review your patch

Not 100% sure aswell, but the probe function is wrong anyway and must be fixed by this patch, so LGTM.

Neil

Best regards,
Martin
