Subject: [PATCH] drm/virtio: pass virtio_gpu_object to virtio_gpu_cmd_transfer_to_host_{2d,3d}
Date:   Thu, 20 Sep 2018 08:29:23 +0200
Message-Id: <20180920062924.6514-1-kraxel@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Pass virtio_gpu_object down to virtio_gpu_cmd_transfer_to_host_2d and
virtio_gpu_cmd_transfer_to_host_3d functions, instead of passing just
the virtio resource handle.

This is needed to lookup the scatter list of the object, for dma sync.
