Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/…

…kernel/git/daeinki/drm-exynos into drm-next

   This pull request includes comprehensive cleanups to HDMI part and
   several fixups. In addition, this pull request includes also a defconfig
   patch which enables mixer driver as default. For this, I got already
   Acked-by from Krzysztof Kozlowski who is a Exynos SoC maintainer.
