Hi Mark
Current snd_soc_component_driver is using snd_pcm_ops. But, it is mainly for ALSA, thus, it not good much to ALSA SoC.
For example .open case (1)(2), each callback can't know it is called for which component. Thus, it need to use using snd_soc_rtdcom_lookup() (3).
--- ALSA SoC --- ... if (component->driver->ops && component->driver->ops->open) (1) return component->driver->ops->open(substream); ...
--- driver --- (2) static int xxx_open(struct snd_pcm_substream *substream) { struct snd_soc_pcm_runtime *rtd = substream->private_data; (3) struct snd_soc_component *component = snd_soc_rtdcom_lookup(..); ... }
It works today, but, will not work in the future if we support multi CPU/Codec/Platform, because 1 rtd might have multiple components which have same driver name. In other words snd_soc_rtdcom_lookup() doesn't work correctly in the future.
To solve this issue, each callback needs to be called with component. This patch copies each snd_pcm_ops member under component driver, and having "component" as parameter.
--- ALSA SoC --- ... if (component->driver->open) => return component->driver->open(component, substream); ...
--- driver --- => static int xxx_open(struct snd_soc_component *component, struct snd_pcm_substream *substream) { ... }
