Subject: [PATCH 3.13 003/160] drm/radeon: fix audio pin counts for DCE6+ (v2)

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

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

From: Alex Deucher <alexdeucher@...il.com>

commit be0949f5eb9c8133a05cf25f108f09e85e79cd32 upstream.

There is actually quite a bit of variance based on
the asic.

v2: fix typo noticed by Jerome.
