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.
