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

[Arnd Bergmann]

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.

[PATCH 2/2] pinctrl: ns2: rename pinctrl_utils_dt_free_map

[Arnd Bergmann]

A conflict of two patches caused a build error when a function got renamed
but a new user appeared in the other patch:

drivers/pinctrl/bcm/pinctrl-ns2-mux.c:540:17: error: 'pinctrl_utils_dt_free_map' undeclared here (not in a function)
  .dt_free_map = pinctrl_utils_dt_free_map,
                 ^~~~~~~~~~~~~~~~~~~~~~~~~

This renames the new user of pinctrl_utils_dt_free_map accordingly.

Sorry for taking so long. Mail Swamp.
