    Subject[15/34] ALSA: hda: Fix 0 dB for Lenovo models using Conexant CX20549 (Venice)
    2.6.34-stable review patch.  If anyone has any objections, please let us know.

    ------------------
    From: Daniel T Chen <crimsun@ubuntu.com>

    commit 0ebf9e3692d640917fb792a7494d05e1f5b1058f upstream.

    Reference: http://mailman.alsa-project.org/pipermail/alsa-devel/2010-May/027525.html

    As reported on the mailing list, we also need to cap to the 0 dB offset
    for Lenovo models, else the sound will be distorted.
