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" * tag 'audit-pr-20221107' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: fix undefined behavior in bit shift for AUDIT_BIT
