Takashi Iwai 20ca63e096 ALSA: seq: Remove spurious WARN_ON() at timer check ...

commit 43a3542870 upstream.

The use of snd_BUG_ON() in ALSA sequencer timer may lead to a spurious
WARN_ON() when a slave timer is deployed as its backend and a
corresponding master timer stops meanwhile.  The symptom was triggered
by syzkaller spontaneously.

Since the NULL timer is valid there, rip off snd_BUG_ON().
