Subject: [45/70] ALSA: HDA: Do not announce false surround in Conexant auto

2.6.37-stable review patch.  If anyone has any objections, please let us know.

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

From: David Henningsson <david.henningsson@...onical.com>

commit 89724958e5d596bb91328644c97dd80399443e87 upstream.

Without this patch, one line-out and one speaker and
Conexant's auto parser would announce (non-working) surround
capabilities.
