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.

In hda_codec.

static void process_unsol_events(struct work_struct *work) { ..... if (codec && codec->patch_ops.unsol_event) codec->patch_ops.unsol_event(codec, res);
