Zero-length arrays are deprecated[1] and we are moving towards adopting C99 flexible-array members instead. So, replace zero-length array declaration in struct nvfw_hs_load_header_v2 with flex-array member. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [2].

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
