Right. grepping for "of_reset_control_get", there seem to be are a few
other drivers that might share the same issue...

Do you mean of_reset_control_get()? Maybe you could switch to
of_reset_control_get_exclusive() while at it?

That one might warrant a devres helper if other drivers were to adopt
the same pattern.

The patch itself looks fine to me,
