Subject[PATCH 1/2] pinctrl: nomadik: hide nmk_gpio_get_mode when unused
Date
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.
