[PATCH 05/10] drm/virtio: use struct to pass params to virtio_gpu_object_create()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Create virtio_gpu_object_params, use that to pass object parameters to
virtio_gpu_object_create.  Also drop unused "kernel" parameter (unused,
always false).
