    Subject[patch 03/55] ASoC: wm_hubs: Enable line out VMID buffer for single ended line outputs
    3.0-stable review patch.  If anyone has any objections, please let me know.

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

    From: Mark Brown <broonie@opensource.wolfsonmicro.com>

    commit 77231abe55433aa17eca712718745275853fa66d upstream.

    For optimal performance the single ended line outputs require that the
    line output VMID buffer be enabled.
