The Linux gpio-keys driver bindings allow for GPIO attached or interrupt attached keys. Currently if an interrupt attached key is encountered gpio_keys_button_probe() will fail due to not being able to get a gpio descriptor: gpio-keys: probe of gpio-keys failed with error -2 Skip the failure in the case of interrupt attached keys to resolve this.
