Subject: video: fbdev: pxafb: potential NULL dereference on error
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit e0299908d606a99e7ffb467bc3c11dfe54133af3 upstream.
If we "goto out;" then it calls display_timings_release(timings);
Since "timings" is NULL, that's going to oops. Just return directly.
