From: Ankitprasad Sharma <ankitprasad.r.sha...@intel.com>i915_gem_object_get_dma_address function is used to retrieve the dma address of a particular page so as to map it in a given GTT entry for CPU access. This function would be used for stolen backed objects also for tasks like pwrite, clearing of the pages etc. So the obj->get_page.sg needs to be initialized for the stolen objects also.
