understood, I think I saw this in the original syzbot mail as well,
but I was hesitant to actually add the tag because the fix was
based on code-inspection only, and I would have felt more comfortable
about asserting the Reported-by if I'd done a clear-cut before/after
verification.

btw, checkpatch.pl complains about the syzbot*@syzkaller.appspotmail.com
addresses as "Unrecognized email address", we should fix that
error from checkpatch at some point.
