Little patch series doing some cleanups in the virtio driver. Patches #1 + #2 have been on the list before as single patches, includes here again for patch dependency reasons.
please review, Gerd
Gerd Hoffmann (5): drm/virtio: print a single line with device features drm/virtio: move byteorder handling into virtio_gpu_cmd_transfer_to_host_2d function drm/virtio: fix byteorder handling in virtio_gpu_cmd_transfer_{from,to}_host_3d functions drm/virtio: Simplify virtio_gpu_primary_plane_update workflow. drm/virtio: factor out virtio_gpu_update_dumb_bo

In theory this change is incompatible on bigendian machines, but in practice 3d acceleration is supported only on little endian machines, so the affected code paths never run on bigendian machines.

Return early for the no framebuffer (or disabled output) case. Results in a simpler code flow for the remaining cases. No functional change.
