  I had just received:
  $ scripts/checkpatch.pl 0001-splice-always-fsnotify_access-in-fsnotify_modify-out.patch
  WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: gpg: Signatu (":35 CEST")'
  #25:
  Fixes: 983652c69199 ("splice: report related fsnotify events")

  total: 0 errors, 1 warnings, 60 lines checked

  NOTE: For some of the reported defects, checkpatch may be able to
        mechanically convert to the typical style using --fix or --fix-inplace.

  0001-splice-always-fsnotify_access-in-fsnotify_modify-out.patch has style problems, please review.

  NOTE: If any of the errors are false positives, please report
        them to the maintainer, see CHECKPATCH in MAINTAINERS.

This fails when the Fixes:ed SHAs are signed, since the output is
  $ git log --format='%H %s'

The fix mimics what was done in commit f24fb53984cf ("perf tools: Don't
include signature in version strings"): just don't ask for the
signatures being validated.

With this, my patch passed validation.
