I wrote the below code

    config = config.get(DOMAIN)
    if ((not config.get(DEVICE_DESCRIPTOR)) and (not config.get(DEVICE_NAME))):
        _LOGGER.error('No    device_descriptor    or    device_name    found')
        return
    keyboard_remote = KeyboardRemote(hass, config)
    def _start_keyboard_remote(_event):
        keyboard_remote.run()
    def _stop_keyboard_remote(_event):
        keyboard_remote.stopped.set()
    hass.bus.listen_once(EVENT_HOMEASSISTANT_START, _start_keyboard_remote)
    hass.bus.listen_once(EVENT_HOMEASSISTANT_STOP, _stop_keyboard_remote)
    return True

What's a good function header?
