-------------------
This is a commit scheduled for the next v2.6.34 longterm release.
http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git
If you see a problem with using this for longterm, please comment.
-------------------

commit b686453543fd56332e8730a2abd7bf5bca756149 upstream.

Most of Intel controllers work as generic HD-audio without quirks,
and it'll be hopefully so in future. Let's mark pci id with the
PCI_CLASS_MULTIMEDIA_HD_AUDIO for Intel so that the driver will work
with any new control chips in future.
