-Subject: [PATCH] pinctrl: Add devm_ apis for pinctrl_{register, unregister}
-
-Add device managed APIs devm_pinctrl_register() and
-devm_pinctrl_unregister() for the APIs pinctrl_register()
-and pinctrl_unregister().
-
-This helps in reducing code in error path and sometimes
-removal of .remove callback for driver unbind.
