This now breaks linux-next. I think the above defines are missing
their include.

My testing wasn't happy either because it couldn't find
marvell,mmp2.h. I guess that's somewhere in linux-next and now we're
on to the secondary issue. Once that's fixed, then the schema checks
will actually run (hint: make sure they pass).

Please get this fixed or revert before it is sent to Linus. Maybe we
can have an rc1 without the schema broken.
