    Subject[PATCH AUTOSEL 5.5 439/542] ALSA: hda - Add docking station support for Lenovo Thinkpad T420s
    Date
    From: Peter Große <pegro@friiks.de>

    [ Upstream commit ef7d84caa5928b40b1c93a26dbe5a3f12737c6ab ]

    Lenovo Thinkpad T420s uses the same codec as T420, so apply the
    same quirk to enable audio output on a docking station.
