From a973bea11c91bf8283cc13eb17d3ef7086f679d6 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 18 Apr 2013 11:32:16 -0400 Subject: drm/radeon: switch audio handling to use callbacks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Register audio callbacks for asic where we support audio. Cleans up the code and makes it easier to add support for newer asics.
