    Subject[PATCH 3.19.y-ckt 090/170] ALSA: intel8x0: Add clock quirk entry for AD1981B on IBM ThinkPad X41.
    Date
    3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

    ---8<------------------------------------------------------------

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

    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.
