    ALSA: HDA: conexant support for Lenovo T520/W520 · ca201c09
    Daniel Suchy authored
    This is patch for Conexant codec of Intel HDA driver, adding new quirk
    for Lenovo Thinkpad T520 and W520. Conexant autodetection works fine for
    T520 (similar subsystem ID is used also in W520 model) and detects more
    mixer features compared to generic (fallback) Lenovo quirk with
    hardcoded options in Conexant codec.
    Patch was activelly tested with Linux 3.0.4, 3.0.6 and 3.0.7 without any
