media: rc: ensure close() is called on rc_unregister_device
If userspace has an open file descriptor on the rc input device or lirc device when rc_unregister_device() is called, then the rc close() is never called. This ensures that the receiver is turned off on the nuvoton-cir driver during shutdown. Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
