Eh, no need. That sort of information doesn't belong in the changelog because
when this code is merged it will be a natural sequence. The cover letter
explicitly calls out that this needs the kernel patches[*]. A footnote could be
added, but asking Isaku and co. to document every external dependency is asking
too much IMO.
