While applying this patch with dim on drm-misc-next, dim push-branch
failed because:

  dim: ERROR: cb86408b1fc2 ("list: add list_last_entry_or_null()"): Mandatory Maintainer Acked-by missing., aborting

Looking at the dim code, it is looking for a Reviewed- or Acked-by from
people listed by `scripts/get_maintainer.pl --no-git-fallback -m --nol
--norolestats`. but that command returns an empty string, so it will
never allow me to push.

How can I get that commit pushed to drm-misc-next?

I think `dim push-branch -f` would work: am I supposed to use it?

(not sure my committer rights allow that)
