Sample crash report:
========================================================
WARNING: possible irq lock inversion dependency detected
5.9.0-rc6-next-20200922-syzkaller #0 Not tainted
--------------------------------------------------------
swapper/1/0 just changed the state of lock:
ffff888099dbb108 (&group->lock){..-.}-{2:2}, at: _snd_pcm_stream_lock_irqsave+0x9f/0xd0 sound/core/pcm_native.c:170
but this lock took another, SOFTIRQ-READ-unsafe lock in the past:
 (&card->ctl_files_rwlock){.+.+}-{2:2}


and interrupts could create inverse lock ordering between them.


other info that might help us debug this:
 Possible interrupt unsafe locking scenario:
