ASoC is using many lists. Now, used dai_link is listed to card as dai_link_list.
[card]->[dai_link]->[dai_link]->...
This "dai_link" is used to create "rtd". And this rtd is listed to card as rtd_list.
[card]->[rtd]->[rtd]->...
Here, each rtd has dai_link. This means, we can track all dai_link via rtd list. This patch removes card dai_link_list, and uses rtd_list instead of it.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
Sound card disconnecting operation was needed when "sound driver" was unbinded without unbinding "sound card". In such case, sound driver should be stopped even though it was playbacking/capturing. Otherwise clock open/close counter mismatch happen.
One headache was that we can't skip unbind in error case because unbind operation doesn't check return value from each drivers. snd_soc_disconnect_sync() was added for these purpose, and Renesas sound card only is used it.
But now, ALSA SoC automatically disconnect sound card when sound driver was unbinded. Thus, snd_soc_disconnect_sync() is no longer needed. This patch removes it.

No driver is using snd_soc_get_dai_substream(), and snd_soc_get_pcm_runtime() is enough for such purpose. We can revival it if it was needed in the future. Let's remove unused function.

Current snd_soc_get_pcm_runtime() is finding rtd by checking dai_link name. But, it is strange and waste of CPU power, because its user want to get rtd from dai_link, not from its name. This patch find rtd via dai_link pointer instead of its name.

Now soc-core and soc-topology is using snd_soc_add_dai_link(). It sounds like dai_link function. But, it creates new pcm_runtime (= rtd), and connect it to card. The purpose is adding pcm_runtime, not dai_link. This patch renames function name.

this function seems to have 2 purposes, dai_link operations and pcm_runtime creation.

soc-core is using soc_link_init(). It sounds like dai_link function, but it is for pcm_runtime.
This patch renames soc_link_init() to soc_init_pcm_runtime(), and checks missing return value.

might be better to first introduce the error check (functional change), then rename?

Current soc_set_name_prefix() for loop is checking both codec_conf pointer and its number
for (...; i < card->num_configs && card->codec_conf; ...)
But, if card->num_configs exists but card->codec_conf was NULL, it is just bug. This patch cleanups for loop condition.

Component device_node is not related to codec_conf loop at soc_set_name_prefix(). This patch moves it to out of loop.

Hi Mark
These are soc-core cleanup step6. These doesn't add new features.
Looks mostly good to me, I only have a set of nit-picks.

Hi Pierre-Louis
Thank you for reviewing, and testing
These are soc-core cleanup step6. These doesn't add new features.
Looks mostly good to me, I only have a set of nit-picks.
First tests look ok (2 known/unrelated errors) https://sof-ci.01.org/linuxpr/PR1538/build2542/devicetest/
Sounds promising, thanks for all this Morimoto-san.
I will fixup and re-post patches.
