From: Kuninori Morimoto <kuninori.morimoto.gx at 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.
