This way the driver doesn't see an error when disabling an always-on regulator. This patch is needed since the commit f93fab312615 ("Revert 'power: regulator: Return success on attempt to disable an always-on regulator'") and use the API introduced by commit cc4a224af226 ("power: regulator: Introduce regulator_set_enable_if_allowed api").
