There is very little difference between this an the previous version
[1]. Maybe could have kept Rob Clark's Acked-by? The only change
was:

- gpu->icc_path = of_icc_get(dev, "gfx-mem");
+ gpu->icc_path = of_icc_get(dev, NULL);

Also: I assume that this is still intended to go through Georgi's tree?
