Interesting. The relevant code flow should be like:
intel_audio_codec_enable()
-> acomp->audio_ops->pin_eld_notify()
-> intel_pin_eld_notify()
-> check_presence_and_report()
-> hdmi_present_sense()
-> sync_eld_via_acomp()
-> snd_hdac_acomp_get_eld()
-> i915_audio_component_get_eld()
So, at first, check whether intel_dig_port in both
intel_audio_codec_enable() and i915_audio_component_get_eld() points
to the same object address. The audio_connector must be set in
intel_audio_codec_enable(), thus basically it must be non-NULL at
i915_audio_component_get_eld(), too.
