WARNING: possible irq lock inversion dependency detected
5.9.0-syzkaller #0 Not tainted
--------------------------------------------------------
syz-executor.5/7446 just changed the state of lock:
ffff888099da5108 (&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:
