whoops, it's not that simple:

Seems that we can only depend on or select some symbol - we run into
huge trouble if thats mixed. Just changed DRM_VIRTIO_GPU to just select
VIRIO instead of depending on it, and now it works.
I've posted another patch for fixing drivers/gpu/drm/virtio/Kconfig
to use 'select' instead of 'depends on'.
