It's not a huge deal, but above your Signed-off-by you could have added:

Suggested-by: Douglas Anderson <dianders@...omium.org>

...since this was my suggestion [1].

One other nit is that the ${SUBJECT} tag should have had the prefix
"kdb:" instead of "KDB:" (AKA not all caps) just based on doing a "git
log" on other changes to that file and seeing what they were doing.
It's not always obvious what the tag should be, but in this case I
think it's fairly consistent.

Everything here is just a nit, so:

Reviewed-by: Douglas Anderson <dianders@...omium.org>

If you want, you could post a v2 adding the "Suggested-by" and fixing
the subject, but it's probably not a big deal. If Daniel cares then
he'll either ask you to post a v2 or fix it himself when applying. If
you do post a v2, you'll want to carry my "Reviewed-by" tag and add it
right above your "Signed-off-by" tag.
