Did you try building this change?
CC [M] drivers/input/keyboard/gpio_keys.o
drivers/input/keyboard/gpio_keys.c: In function ‘gpio_keys_setup_key’:
drivers/input/keyboard/gpio_keys.c:509:2: error: assignment of member
‘type’ in read-only object
button->type = button->type ?: EV_KEY;
^
make[1]: *** [drivers/input/keyboard/gpio_keys.o] Error 1
make: *** [drivers/input/keyboard/gpio_keys.o] Error 2
