drm/i915: Avoid pointer arithmetic in calculating plane surface offset commit 44eb0cb9620c6a53ec8e7073262e2af8079b727f upstream. VMA offsets are 64 bits. Plane surface offsets are in ggtt and the hardware register to set this is thus 32 bits. Be explicit about these and convert carefully to from vma to final size. This will make sparse happy by not creating 32bit pointers out of 64bit vma offsets.
