This also highlights a bit of an issue with vfio-platform, who is to be the sub-maintainer? Is it you? Antonios? Me? I can't even test this code, so I'm hoping there's someone signed up to prevent this code from immediately bit rotting.

Also, trying to merge your branch below (after fixing the URL), I get some conflicts with the current mainline, so that's a bit of a show stopper too. Can you start by rebasing on top of 4.0-rc1 with all the dependencies, reposting the series, and cc-ing the original author of the patches (as I cannot see Antonios on the CC list)?
