[PATCH 1/2] [v2] drm/nouveau: retain device pointer in nvkm_gsp_mem object
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.
