Subject: [PATCH 3.12 71/98] ALSA: intel8x0: Add clock quirk entry for AD1981B on IBM ThinkPad X41.

From: "Vittorio Gambaletta (VittGam)" <linuxbugs@...tgam.net>

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

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

commit 4061db03dd71d195b9973ee466f6ed32f6a3fc16 upstream.

The clock measurement on the AC'97 audio card found in the IBM ThinkPad X41
will often fail, so add a quirk entry to fix it.
