From: Takashi Iwai <tiwai@suse.de>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit 77f07800cb456bed6e5c345e6e4e83e8eda62437 upstream.

The recent Intel H97/Z97 chipsets need the similar setups like other
Intel chipsets for snooping, etc. Especially without snooping, the
audio playback stutters or gets corrupted. This fix patch just adds
the corresponding PCI ID entry with the proper flags.
