pinctrl: nomadik: hide nmk_gpio_get_mode when unused
nmk_gpio_get_mode is only used in one place, and that is conditionally compiled if DEBUG_FS is enabled. A recent cleanup has marked the definition 'static', which now leads to a warning: drivers/pinctrl/nomadik/pinctrl-nomadik.c:614:12: error: 'nmk_gpio_get_mode' defined but not used [-Werror=unused-function] static int nmk_gpio_get_mode(struct nmk_gpio_chip *nmk_chip, int offset) ^~~~~~~~~~~~~~~~~ Moving the function itself inside the #ifdef shuts it up again. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: 5e81e0a0913c ("pinctrl: nomadik: use BIT() with offsets consequently") Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
