Subject: [PATCH] [UBUNTU:sound/pci/] #68659: Disable DXS explicitly for 0x1458a002 (VIA-based)

UpstreamStatus: Not yet merged

References:	Ubuntu: #68659, #68876
		Debian: #366212
		ALSA: #2067
		http://hg-mirror.alsa-project.org/alsa-kernel?cs=5cf914368b6e;style=raw

As the two referenced Ubuntu bug reports testify, using VIA_DXS_SRC
by default is insufficient and results in errors such as
"Sound server fatal error: cpu overload, aborting". This patch
explicitly disables DXS for a known broken ID (despite the source
claiming it works).

This commit closes Ubuntu: #68659, #68876.

This commit is applicable to Dapper, Edgy, and Feisty linux-source.
