syzbot has found a reproducer for the following crash on:

HEAD commit: 2747d5fd Add linux-next specific files for 20200116

This looks like a fairly old head, and missing the fix that is already included in 5.5 release: 60adcfde92fa40fcb2dbf7cc52f9b096e0cd109a ALSA: seq: Fix racy access for queue timer in proc read
