Hans Verkuil 2781b86d7e media: cec: forgot to cancel delayed work ... commit 490d84f6d7 upstream. If the wait for completion was interrupted, then make sure to cancel any delayed work. This can only happen if a transmit is waiting for a reply, and you press Ctrl-C or reboot/poweroff or something like that which interrupts the thread waiting for the reply and then proceeds to delete the CEC message. Since the delayed work wasn't canceled, once it would trigger it referred to stale data and resulted in a kernel oops.
