> Subject: [PATCH 2/3] drm/i915: Move audio_connector to intel_encoder
>
> With DP MST, a digital_port can carry more than one audio stream. Hence,
> more than one audio_connector needs to be attached to intel_digital_port in
> such cases. However, each stream is associated with an unique encoder. So,
> instead of creating an array of audio_connectors per port, move
> audio_connector from struct intel_digital_port to struct intel_encoder.
> This also simplifies access to the right audio_connector from codec functions
> in intel_audio.c that receive intel_encoder.
