I changed that code yesterday with a little bit more comment.

Wei, Peer, could you regenerate the patch based on the latest sound
git tree?

    git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git

or use the snapshot tarball from

    ftp://ftp.kernel.org/pub/linux/tiwai/snapshot/

This already contains the fix for the 4th slot probe on Nvidia
chipset.


thanks,

Takashi
