I think the real fix is to provide some more documentation on
scripts/parse-maintainers.pl that explains how to run this script when
an author hits the warning type in checkpatch.pl.
I see these follow-up patches:
- some documentation on scripts/parse-maintainers.pl
- a patch to checkpatch.pl that points out this documentation when
this warning occurs.
- maybe: improve of scripts/parse-maintainers.pl to handle exactly
this use case of a patch author (assuming that the patch was just
created with git format-patch -1) and how to get the corrected diff
for this patch.
- maybe: a patch to checkpatch.pl that can create the command for
scripts/parse-maintainers.pl for a specific patch and which then can
be added with git commit --amend or git commit && git rebase and
squashing that in.
I think once that is done and better understood, you can much better
judge if there is really a need for a fix in checkpatch.pl.
