Re: [alsa-devel] [PATCH 08/12] ASoC: SOF: Generic probe compress operations

+int sof_probe_compr_open(struct snd_compr_stream *cstream,

• struct snd_soc_dai *dai)
  

+{

• struct snd_sof_dev *sdev =

• 		snd_soc_component_get_drvdata(dai->component);
  

• int ret;
• ret = snd_sof_probe_compr_assign(sdev, cstream, dai);
• if (ret < 0) {

• dev_err(dai->dev, "Failed to assign probe stream: %d\n", ret);
  

• return ret;
  

• }
• sdev->extractor = ret;

could you either rename the 'extractor' field to something meaningful or add a comment on what is stored in this field? A stream tag? a device number? It's only used once for the init.
