[PATCH 6/6] drm: fourcc byteorder: virtio restrict to XRGB8888
While wading through the code I've noticed we have a little issue in
virtio: We attach a format to the bo when it is created
(DRM_IOCTL_MODE_CREATE_DUMB), not when we map it as framebuffer
(DRM_IOCTL_MODE_ADDFB).
Easy way out: support a single format only.

[PATCH v2 6/6] drm/virtio: fix DRM_FORMAT_* handling
...because of broken drm_mode_addfb() behavior. So with
drm_mode_addfb() being fixed we can fix this too.
While wading through the code I've noticed we have a little issue in
virtio: We attach a format to the bo when it is created
(DRM_IOCTL_MODE_CREATE_DUMB), not when we map it as framebuffer
(DRM_IOCTL_MODE_ADDFB). Easy way out: Support a single format only.
Pick DRM_FORMAT_HOST_XRGB8888, it is the only one actually used in
practice. Drop unused mappings in virtio_gpu_translate_format().
With this patch applied both ADDFB and ADDFB2 ioctls work correctly in
the virtio-gpu.ko driver on big endian machine...
