I think you'll find this is too strict. There may be subtle differences
in the author (which comes from the patch email From: header) and
signed-off-by lines.

If you write a patch and I review and push it, I won't add an extra
reviewed-by, just a signed-off-by.

This should be added to the checkpatch part instead of push. First, we
need to push a lot of non-i915 stuff when rebasing fixes or pushing
backmerges. Second, it is useful to be able to non-intrusively check
this before pushing.
