gpiolib: Add missing dummies for the unified device properties interface
commit 496e7ce2a46562938edcb74f65b26068ee8895f6 upstream. If GPIOLIB=n: drivers/leds/leds-gpio.c: In function ‘gpio_leds_create’: drivers/leds/leds-gpio.c:187: error: implicit declaration of function ‘devm_get_gpiod_from_child’ drivers/leds/leds-gpio.c:187: warning: assignment makes pointer from integer without a cast Add dummies for fwnode_get_named_gpiod() and devm_get_gpiod_from_child() for the !GPIOLIB case to fix this. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Fixes: 40b7318319281b1b ("gpio: Support for unified device properties interface") Acked-by: Alexandre Courbot <acourbot@nvidia.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Bryan Wu <cooloney@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
