Subject: [009/129] ALSA: HDA: Fix master control for Cirrus Logic 421X

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

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

commit 40d03e63e91af8ddccdfd5a536cc2a6e51433e1d upstream.

The control name "HP/Speakers" is non-standard, and since there is
only one DAC on this chip there is no need for a virtual master
anyway.
