The intention of checking obj->gtt_offset!=0 is to verify that the target object was listed in the execbuffer and had been bound into the GTT. This is guarranteed by the earlier rearrangement to split the execbuffer operation into reserve and relocation phases and then verified by the check that the target handle had been processed during the reservation phase. However, the actual checking of obj->gtt_offset==0 is bogus as we can indeed reference an object at offset 0. For instance, the framebuffer installed by the BIOS often resides at offset 0 - causing EINVAL as we legimately try to render using the stolen fb.
