From 807a7515aea421f2b340140482ed4c8811c523c6 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 7 Jan 2010 17:45:03 +0200 Subject: [PATCH] OMAP: DSS2: OMAPFB: fix crash when panel driver was not loaded If the panel's probe had failed, omapfb would still go on, eventually crashing. A better fix would be to handle each display properly, and leaving just the failed display out. But that is a bigger change.
