This is a note to let you know that I have just added a patch titled drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.3. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From aee389b0e2e0d99c1ac779804fc46c2921b405d6 Mon Sep 17 00:00:00 2001 From: Egbert Eich <eich@suse.de> Date: Tue, 4 Jun 2013 17:13:21 +0200 Subject: drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC. commit 53d3b4d7778daf15900867336c85d3f8dd70600c upstream. In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used for DDC. Thus the code will always have to rely on a LVDS panel mode supplied by VBT. In most cases this succeeds, so this didn't get detected for quite a while.
