    ASoC: Support registering a DAI dynamically · 68003e6c
    Mengdong Lin authored
    Define API snd_soc_register_dai() to add a DAI dynamically and
    create the DAI widgets. Topology can use this API to register DAIs
    when probing a component with topology info. These DAIs's playback
    & capture widgets will be freed when the sound card is unregistered
    and the DAIs will be freed when cleaning up the component.
    And a dobj is embedded into the struct snd_soc_dai_driver. Topology
    can use the dobj to find the DAI drivers created by it and free them
    when the topology component is removed.
