Merge tag 'audit-pr-20221107' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit
Pull audit fix from Paul Moore:
"A small audit patch to fix an instance of undefined behavior in a
shift operator caused when shifting a signed value too far, the same
case as the lsm patch merged previously.
While the fix is trivial and I can't imagine it causing a problem in a
backport, I'm not explicitly marking it for stable on the off chance
that there is some system out there which is relying on some wonky
unexpected behavior which this patch could break; *if* it does break,
IMO it's better that to happen in a minor or -rcX release and not in a
stable backport"
