Hi Mark Many ASoC drivers are getting rtd from substream by rtd = substream->private_data OTOH, we have snd_pcm_substream_chip() macro for it. #define snd_pcm_substream_chip(substream) ((substream)->private_data) But, both are not understandable for reader. This patch adds new asoc_substream_to_rtd() which is easy to understand. These are not important, but for readable code. Kuninori Morimoto (29): ASoC: soc-xxx: add asoc_substream_to_rtd() ASoC: ux500: use asoc_substream_to_rtd() ASoC: ti: use asoc_substream_to_rtd() ASoC: tegra: use asoc_substream_to_rtd() ASoC: sunxi:
