2.6.28-rc2-mm1 - sound semi-busted on Dell Latitude D820

From: Valdis . Kletnieks
Date: Mon Nov 10 2008 - 14:36:55 EST

Sometime between -mmotm1017 and -rc2-mm1, something odd happened to the
sound subsystem. On my Dell Latitude D820, audio works OK if it's sitting
there standalone, or in its docking station.

However, when I plug in headphones, it goes silent.

Sorry for not having any more detail, but I've not had a chance to bisect
this down to a specific commit.

I did run alsa-info for the two kernels, here's a diff between them. I also
attached a copy of the full output for working -mmotm1017.

(- lines are working -mmotm-1017, + are busted -rc2-mm1)

Looks like it lost the bits that setup the headphone jack.
