If that's going to be overwritten in the DTS, maybe we should just
drop it from the DTSI.

The rest of the serie looks good to me, however, it is a best practice
to have a changelog either in the cover letter (if you have one) or in
the patches themselves so that reviewer know what changed between the
two versions.
