Subject: [PATCH 49/93] drm/radeon: fix LCD record parsing
3.8.13.10 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@....com>
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.
