From: Pali Rohár Date: Fri, 5 Aug 2022 12:22:01 +0000 (+0200) Subject: pinctrl: armada-37xx: Checks for errors in gpio_request_enable callback X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6b262b32faf0abf74062e2e2b72cbbea4572b9f3;p=linux.git pinctrl: armada-37xx: Checks for errors in gpio_request_enable callback Now when all MPP pins are properly defined and every MPP pin has GPIO function, always checks for errors in armada_37xx_gpio_request_enable() function when calling armada_37xx_pmx_set_by_name(). Function armada_37xx_pmx_set_by_name() should not return "not supported" error anymore for any GPIO pin when requesting GPIO mode.
