This is a note to let you know that I have just added a patch titled drm/radeon: improve dac adjust heuristics for legacy pdac to the linux-3.5.y-queue branch of the 3.5.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-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From fe16f2a1f248521dd7104b2e9873f2018b702dd1 Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexander.deucher@amd.com> Date: Fri, 19 Jul 2013 17:44:43 -0400 Subject: [PATCH] drm/radeon: improve dac adjust heuristics for legacy pdac commit 03ed8cf9b28d886c64c7e705c7bb1a365fd8fb95 upstream. Hopefully avoid more quirks in the future due to bogus vbios dac data.
