So it turns out there are a couple problems.

1) This patch is missing:

http://patchwork.ozlabs.org/patch/128533/

Our exalted maintainer apparently forgot to apply this patch in a timely
manner for 3.3, so it probably won't make it.  But that's something I'll
just have to deal with.

2) The p1022_ds.c needs the equivalent of this patch:

http://mailman.alsa-project.org/pipermail/alsa-devel/2011-November/046253.html

I have no idea how the P1022DS ever worked, because the WM8776 driver has
always needed the SND_SOC_DAIFMT_Cxx_xxx macro defined.

Apparently, p1022_ds.c needs to set a value for SND_SOC_DAIFMT_INV_MASK.
I tried SND_SOC_DAIFMT_NB_NF, and that seems to work.

Shawn, I'd make the change myself, but I don't want to step on your toes
while doing it.  Do you want to make it yourself?
