media: rc: oops in ir_timer_keyup after device unplug
If there is IR in the raw kfifo when ir_raw_event_unregister() is called, then kthread_stop() causes ir_raw_event_thread to be scheduled, decode some scancodes and re-arm timer_keyup. The timer_keyup then fires when the rc device is long gone. Cc: stable@vger.kernel.org Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
