Subject: pinctrl: airoha: Fix return value in pinconf callbacks
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=563fcd6475931c5c8c652a4dd548256314cc87ed;p=users%2Fjedix%2Flinux-maple.git

pinctrl: airoha: Fix return value in pinconf callbacks

Pinctrl stack requires ENOTSUPP error code if the parameter is not
supported by the pinctrl driver. Fix the returned error code in pinconf
callbacks if the operation is not supported.

Fixes: 1c8ace2d0725 ("pinctrl: airoha: Add support for EN7581 SoC")
