[PATCH 01/15] pinctrl: samsung: Detect and handle unsupported configuration types
This patch modifies the pinctrl-samsung driver to detect when width of a bit field is set to zero (which means that such configuraton type is not supported) and return an error instead of trying to modify an inexistent register.
