[alsa-devel] [PATCH v2 1/7] ASoC: soc-core: remove snd_soc_rtdcom_list

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com

Current ALSA SoC is using struct snd_soc_rtdcom_list to connecting component to rtd by using list_head.

struct snd_soc_rtdcom_list { struct snd_soc_component *component; struct list_head list; /* rtd::component_list */ };

struct snd_soc_pcm_runtime { ... struct list_head component_list; /* list of connected components */ ... };

The CPU/Codec/Platform component which will be connected to rtd (a) is indicated via dai_link at snd_soc_add_pcm_runtime()

int snd_soc_add_pcm_runtime(...) { ... /* Find CPU from registered CPUs */ rtd->cpu_dai = snd_soc_find_dai(dai_link->cpus); ... (a) snd_soc_rtdcom_add(rtd, rtd->cpu_dai->component); ...

/* Find CODEC from registered CODECs */ (b) for_each_link_codecs(dai_link, i, codec) { rtd->codec_dais[i] = snd_soc_find_dai(codec); ... (a) snd_soc_rtdcom_add(rtd, rtd->codec_dais[i]->component); } ...

/* Find PLATFORM from registered PLATFORMs */ (b) for_each_link_platforms(dai_link, i, platform) { for_each_component(component) { ... (a) snd_soc_rtdcom_add(rtd, component); } }

}

It shows, it is possible to know how many components will be connected to rtd by using

dai_link->num_cpus dai_link->num_codecs dai_link->num_platforms

If so, we can use component pointer array instead of list_head, in such case, code can be more simple. This patch removes struct snd_soc_rtdcom_list that is only of temporary value, and convert to pointer array.
