Store the struct device pointer used to allocate the DMA buffer in the nvkm_gsp_mem object. This allows nvkm_gsp_mem_dtor() to release the buffer without needing the nvkm_gsp. This is needed so that we can retain DMA buffers even after the nvkm_gsp object is deleted. Signed-off-by: Timur Tabi <ttabi at nvidia.com> --- v2: rebased to drm-misc-next
