[PATCH 3.16.y-ckt 031/170] drm/radeon: fix speaker allocation setup

[Luis Henriques]

3.16.7-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@xxxxxxx>

commit 4910403836ded89803fab201d4b5caaa85de3a89 upstream.

If the sad_count is 0, set the hw to stereo and change
the error message to a warn.  A lot of monitors don't
set the speaker allocation block.
