Your commit message doesn't match your subject.

A couple variants have been documented and only
one should actually be used.

$ git grep -i co-developed-by Documentation/process/
Documentation/process/5.Posting.rst: - Co-developed-by: states that the patch was also created by another developer
Documentation/process/submitting-patches.rst:12) When to use Acked-by:, Cc:, and Co-Developed-by:
Documentation/process/submitting-patches.rst:A Co-Developed-by: states that the patch was also created by another developer

$ git log --grep="co-developed-by:" -i | \
  grep -ohiP "co-developed-by:" | sort | uniq -c | sort -rn
     80 Co-developed-by:
     40 Co-Developed-by:

So which should it be?

btw: I prefer neither as I think Signed-off-by: is sufficient.
