Merge branch 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes

Inki writes:
"As I posted before, we have added a new git repository for Exynos drm
to MAINTAINERS file so change it to new one like below,
   from git://git.infradead.org/users/kmpark/linux-samsung
   to git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos

And this pull request includes the following:
- fix display on issue when user requested dpms mode changing.
- add git repository for Exynos drm to MAINTAINERS file.
- add support for ARCH_MULTIPLATFORM.
- and code clean."

* 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm: exynos: removed warning due to missing typecast for mixer driver data
  drm/exynos: add support for ARCH_MULTIPLATFORM
  MAINTAINERS: Add git repository for Exynos DRM
  drm/exynos: fix display on issue
