From 6d90714d9a0d4b9c5c17952cb5affe7a1e3b6fb3 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 20 Aug 2013 14:59:01 -0400 Subject: [PATCH] drm/radeon: fix LCD record parsing commit 95663948ba22a4be8b99acd67fbf83e86ddffba4 upstream. If the LCD table contains an EDID record, properly account for the edid size when walking through the records. This should fix error messages about unknown LCD records.
