Subject: pinctrl: propagate map validation errors
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fde04f419a230fb7f7dc018a9deca6f5d431831e;p=linux-beck.git

pinctrl: propagate map validation errors

pinctrl_register_map() was returning early if pinmux_validate_map() or
pinconf_validate_map() failed, but was not actually returning the error
code.
