I started working on this when next-20170503 was the latest and forgot
to rebase before sending the patch series. It was actually in both
next-20170502 and 20170503 but not in more recent ones.
Liam told me in a private message he's soon sending a new version of his
patch series, so I'll be waiting for the patches to reappear in next.
Thanks,
Quentin
