Hisashi,
First of all, kraxel is not the current maintainer. Please c/c to me
instead. Also, please copy v4l mailing list. You don't need to c/c LKML
for this kind of patch.

No. Newer patches should be generated against V4L tree. It is available

Am I wrong, or do you have a different audio chip? If so, the best
practice is to create a separate file for handling it (like we have for
msp34xx, wm8775 and others).

No. Today's last board is 0x8f. This is because you've used 2.6.14 instead of the v4l tree.
Cheers,
