Commit f2d347ff70be453e ("Input: gpio_keys - add device tree support for
interrupt only keys") caused the following build warning:
drivers/input/keyboard/gpio_keys.c: In function 'gpio_keys_probe':
drivers/input/keyboard/gpio_keys.c:647:15: warning: 'irq' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/input/keyboard/gpio_keys.c:622:7: note: 'irq' was declared here
Initialize 'irq' with a default value to fix it.
