| 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. |
