This doesn't apply without fuzz, so I don't know what tree you are
working against here.

Please redo it against the latest version of the tty-next tree.

You don't actually need the test here as far as I can see. Providing a
timer has been initialised (init_timer) then running del_timer is safe
even if the timer is not currently queued or has completed.
