drm/i915: Ignore bogus plane coordinates on SKL when the plane is not visibledrm-intel-fixes-2017-01-19
When the plane is invisible we may have all sorts of bogus stuff in the coordinates, which we must ignore or else we might fail the plane update. This started to happen on SKL when I moved the plane offset computation to happen in the check phase. Previously we happily ignored it all since we never called the update_plane hook with an invisible plane.
