Could you please replace s/defined/IS_ENABLED/ and also the #ifdefs with
"if (IS_ENABLED(CONFIG_DRM_VIRTIO_GPU_KMS))" in the code? The ifdefs are
always not nice to have in the code. The IS_ENABLED usage will also make
code compile-tested regardless of the CONFIG_DRM_VIRTIO_GPU_KMS option
state.
Otherwise looks good!
