You cannot base such patch on mainline because you can overwrite (or
disregard) other people's patches already waiting in next. Although we
are just after rc1 so there shouldn't be much new stuff in linux-next
but still - please base on next.

Indeed... and I don't know when it will go there so actually maybe it
should be removed... but in the same time removing DRM_EXYNOS_HDMI
will probably make some conflicts because mentioned patch will go
through Exynos DRM tree or Samsung SoC.
