Merge tag 'audit-pr-20210830' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:
 "Two patches in the audit pull request for v5.15; one is trivial
  ("header protection") but the second is a real patch that fixes a
  refcounting problem.

  The refcount fix normally would have been sent up during the -rcX
  cycle, but since we merged it less than a week before v5.14 proper I
  felt it was better to wait for the merge window to open; the patch is
  marked with the usual -stable markings"
