This commit should be reverted:

Subject: [PATCH] ALSA: hda - Fix redundant jack creations for cx5051

As the patch commit text says,
"The fix is needed only up to 3.2 kernel, since the HD-audio jack layer
was redesigned in the 3.3 kernel."

As we carry that redesigned jack layer, the problem addressed by this 
patch does not apply to our kernel.

Moreover, it seems like one of my patches (ALSA: hda - Integrate 
input-jack stuff into kctl-jack) was modified somehow in this branch to 
make it apply, it seems easier for everybody if I just tell you what to 
do instead of trying to sort that out, which is to:

1) Start with the 3.2.9 tree
2) Revert 2a8e5e8a2df18812c60720fa0534c29c9f1c17b6
3) Rebase on the result, i e, re-apply the jack detection patches (in 
their unmodified versions), together with all the other Ubuntu changes.

Does that make sense?
