[PATCH 1/3] gpiolib: Add missing dummies for the unified device properties interface
From: Geert Uytterhoeven
Date: Thu May 07 2015 - 04:09:12 EST
If GPIOLIB=n:
drivers/leds/leds-gpio.c: In function âgpio_leds_createâ:
drivers/leds/leds-gpio.c:187: error: implicit declaration of function âdevm_get_gpiod_from_childâ
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@xxxxxxxxxxxxxx>
Fixes: 40b7318319281b1b ("gpio: Support for unified device properties interface")
