ASoC: soc-compress: add snd_compress_ops
Current snd_soc_component_driver has compr_ops, and each driver can have callback via it. But, it is mainly created for ALSA, thus, it doesn't have "component" as parameter. Thus, each callback can't know it is called for which component. Each callback currently is getting "component" by using snd_soc_rtdcom_lookup() with driver name. --- ALSA SoC --- ... if (component->driver->compr_ops && component->driver->compr_ops->open) => return component->driver->compr_ops->open(stream); ... --- driver --- static int xxx_open(struct snd_compr_stream *stream) { struct snd_soc_pcm_runtime *rtd = stream->private_data; => 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 same driver name component. To solve this issue, each callback need to be called with component. We already have many component driver callbacks. This patch adds new snd_compress_ops, and call it with "component". --- ALSA SoC --- ... if (component->driver->compress_ops->open) => return component->driver->compress_ops->open( component, substream); ~~~~~~~~~ ... --- driver --- static int xxx_open(struct snd_soc_component *component, struct snd_compr_stream *stream) { => /* it don't need to use snd_soc_rtdcom_lookup() */ ... } Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Charles Keepax <ckeepax@opensource.cirrus.com> Reviewed-by: Charles Keepax <ckeepax@opensource.cirrus.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Link: https://lore.kernel.org/r/87v9luvdmh.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
