Subject: [PATCH 4.8 125/138] video: fbdev: pxafb: potential NULL dereference on error
4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@...cle.com>
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.
Fixes: 420a488278e8 ('video: fbdev: pxafb: initial devicetree conversion')
