[alsa-devel] hda_codec_ops hotplug events

[James Courtier-Dutton]

static struct hda_codec_ops intel_hdmi_patch_ops = {
        .init                   = intel_hdmi_init,
        .free                   = intel_hdmi_free,
        .build_pcms             = intel_hdmi_build_pcms,
        .build_controls         = intel_hdmi_build_controls,
        .unsol_event            = hdmi_unsol_event,
};

What calls .unsol_event ?

It need something to cause this function to be executed.
I cannot seem to find out what calls this.
