Thadeu Lima de Souza Cascardo reports this: Brightness notification does not work until the user writes to hotkey_mask attribute. That's because the polling thread will only run if hotkey_user_mask is set and someone is reading the input device or if hotkey_driver_mask is set. In this second case, this condition is not tested after the mask is changed, because the brightness and volume drivers are started after the hotkey drivers. Fix tpacpi_hotkey_driver_mask_set() to call hotkey_poll_setup(), so that the poller kthread will be started when needed.
