Could we make this return 0, to just skip non-v4l2_subdev entities?
Currently, imx_media_probe_complete silently fails with this -EINVAL if
there is a tvp5150 connected due to the separate media entities that the
tvp5150 driver creates for the input connectors (Composite0, for
example).

Right, I've made that change.
