I tested these patches on a Exynos5800 Peach Pi Chromebook. The
s5p-mfc driver probes correctly and the allocation succeeds.

I also tried to test actual video decoding using Gstreamer but ran
into issues (not related to this series) so testing that won't be
trivial for me.

It shouldn't block Doug's series though IMHO since he tested on his
platform and the patches speeds up allocation there, so is an
improvement.
