| |
Drop open-coded pattern: 'devm_regulator_get(), regulator_enable(), add_action_or_reset(regulator_disable)' and use the devm_regulator_get_enable() and drop the pointer to the regulator. This simplifies code and makes it less tempting to add manual control for the regulator which is also controlled by devm.
