Subject: [072/289] ALSA: HDA: Enable internal mic on Dell E6410 and Dell E6510

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

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

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

[Not upstream as .37 fixes this differently in a much more complete way
that is not able to be backported easily.]

(Ported on top of 2.6.36)
