From: Masahiro Yamada <[email protected]> Currently, pinctrl_register() just returns NULL on error, so the callers can not know the exact reason of the failure.
Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some -ENOMEM on error of pinctrl_register(), although the error code might be different from the real cause of the error. This commit reworks pinctrl_register() to return the appropriate error code and modifies all of the pinctrl drivers to use IS_ERR() for the error checking and PTR_ERR() for getting the error code.
