[PATCH 4.5 082/124] [media] coda: fix error path in case of missing pdata on non-DT platform

Show all headers | View raw

4.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Philipp Zabel <p.zabel@pengutronix.de>

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")
