applied both patches, thanks!

I reworded the subject here too and re-ordered the git trailers, as they
should have a causal order where possible. I.e., if someone else made a
patch, or helped you to do so, their co-authored-by or originally-by is
normally before your signed-off-by, as your "signature" shows that all
above it is (to your best knowledge) correct w.r.t patch ownership and
description, and like on "real" documents that signature goes at the
bottom.
