Subject: [24/27] ALSA: HDA: Fix internal microphone on Dell Studio 16 XPS 1645

2.6.32-longterm review patch.  If anyone has any objections, please let me know.

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

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

commit ffe535edb9a9c5b4d5fe03dfa3d89a1495580f1b upstream.

More than one user reports that changing the model from "both" to
"dmic" makes their Internal Mic work.
