First test of the hda-jack branch

Hi Takashi,

After having some troubles with the kernel scripts (on the Ubuntu side) 
I've managed to try out your test/hda-jack branch. I'm attaching a patch 
I had to apply to make the modules load properly.

After having applied the attached patch, I get stuck at an OOPS, which I 
don't have time to troubleshoot further today. I'm attaching the OOPS 
log as well (alsa-info for the system I'm testing on is the same as I 
sent you a few days ago).

Subject: [PATCH] ALSA: HDA: Jack: Export required functions from hda_jack.c

These two functions are being used by the codec-idt and codec-hdmi
modules, so they need to be exported properly.
