regulator_get calls either of_regulator_get or dev_regulator_get, both of which accept a supply parameter. Only dev_regulator_get gracefully handles a NULL supply by considering all registered regulators.
of_regulator_get on the other hand, will complain at debug level, before returning NULL: uart-pl011 [email protected]: No <NULL>-supply node found, using dummy regulator Avoid this message by skipping of_regulator_get if no supply was found and directly call dev_regulator_get.
