From: Sean Young <sean@xxxxxxxx> [ Upstream commit 8e782fcf78275f505194e767c515202d4fd274bc ] 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.
