4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>
commit bc717d5e92c8c079280eb4acbe335c6f25041aa2 upstream.
If we bail out this early, v4l2_device_register() has not been called
yet, so no need to call v4l2_device_unregister().
Fixes: b7bd660a51f0 ("[media] coda: Call v4l2_device_unregister() from a single location")
