> Initialize audio_comp when audio starts and wait for audio_comp at
> dp_display_disable(). This will take care of both dongle unplugged
> and display off (suspend) cases.
>
> Changes in v2:
> -- add dp_display_signal_audio_start()
>
> Changes in v3:
> -- restore dp_display_handle_plugged_change() at dp_hpd_unplug_handle().
>
> Changes in v4:
> -- none
