I've tried this, but something is wrong: 'media-ctl -p' shows an empty
topology, ditto with contrib/test/mc_nextgen_test.

For the same reason 'v4l2-compliance -M0' fails with:

 fail: v4l2-test-media.cpp(120): !topology.num_entities

I'm not sure what's going on here, but it needs some more work.

In the meantime I'll merge this patch since it doesn't hurt.

Regards,

	Hans
