But, the generic naming of intel_encoder_get_port() sounds like it should handle DDI and Non-DDI platforms. Can we just have intel_encoder_get_port()? IOW, rename intel_ddi_get_encoder_port() to intel_encoder_get_port() and move it out of intel_ddi.c? > > or you could just your own function for intel_audio.c at this time, like: > > static enum port encoder_get_port(encoder) > { > if (encoder->type == MST; > return enc_to_mst()...; > else > return enc_to_dig_port()...; > } > > > > > > > > > { > > > > struct hdac_bus *bus = codec->bus; > > > > struct i915_audio_component *acomp = bus->audio_component; > > > > @@ -212,7 +213,7 @@ int snd_hdac_sync_audio_rate(struct hdac_device *codec, hda_nid_t nid, int rate) > > > > port = pin2port(codec, nid); > > > > if (port < 0) > > > > return -EINVAL; > > > > - return acomp->ops->sync_audio_rate(acomp->dev, port, rate); > > > > + return acomp->ops->sync_audio_rate(acomp->dev, port, pipe, rate); > > > > } > > > > EXPORT_SYMBOL_GPL(snd_hdac_sync_audio_rate); > > > > > > > > @@ -236,7 +237,7 @@ EXPORT_SYMBOL_GPL(snd_hdac_sync_audio_rate); > > > > * thus it may be over @max_bytes.
