This is a note to let you know that I have just added a patch titled drm/radeon: program DCE2 audio dto just like DCE3 to the linux-3.11.y-queue branch of the 3.11.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-3.11.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 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From ba011c6d63b3219c4d78792e7d41a76dbb28b180 Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexander.deucher@amd.com> Date: Mon, 25 Nov 2013 13:20:59 -0500 Subject: drm/radeon: program DCE2 audio dto just like DCE3 commit 55d4e020fb8ddd3896a8cd3351028f5c3a2c4bd3 upstream.
