Guennadi Liakhovetski 7dfff95366 [media] V4L: soc-camera: remove soc-camera bus and devices on it
Now that v4l2 subdevices have got their own device objects, having
one more device in soc-camera clients became redundant and confusing.
This patch removes those devices and the soc-camera bus, they used to
reside on.
