IMPORTANT: if you fix the issue, please add the following tag to the commit: Reported-by: syzbot+23b22dc2e0b81cbfcc95@syzkaller.appspotmail.com Fixes: f3ca3f5b0966 ("dt-bindings: sound: cs42l51: Remove unneeded I2C unit name")
The conclusion that this commit caused the problem is strange, since this commit is just a yaml documentation fix.
The bisection result must be bogus. And the issue here is harmless, merely a superfluous WARN_ON(). I'll work on it later.
thanks,
Takashi
