    Subject[PATCH 4.19 45/52] ALSA: hda/realtek: Enable headset MIC of Acer TravelMate X514-51T with ALC255
    Date
    4.19-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Jian-Hong Pan <jian-hong@endlessm.com>

    commit cbc05fd6708c1744ee6a61cb4c461ff956d30524 upstream.

    The Acer TravelMate X514-51T with ALC255 cannot detect the headset MIC
    until ALC255_FIXUP_ACER_HEADSET_MIC quirk applied. Although, the
    internal DMIC uses another module - snd_soc_skl as the driver. We still
    need the NID 0x1a in the quirk to enable the headset MIC.
