From 4d4b032bd7bb43650a71dd804eb9bbb589d3d818 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 26 Feb 2016 08:21:35 -0300 Subject: [PATCH] coda: fix error path in case of missing pdata on non-DT platform 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().
