Merge commit 'refs/for-upstream/mali-dp' of git://linux-arm.org/linux-ld into drm-next 



This pull requests adds initial Mali D71 support into the Arm "komeda" DRM
driver. The code has been reviewed at the end of last year, I just been
too slow with pushing it into mainline. Since it started baking in
linux-next we had a kbuild-bot issue raised and one from Joe Perches on
the MAINTAINERS entry, for which I'm including fixes here.
