[alsa-devel] [PATCH v2 00/14] ASoC: soc-core cleanup - step 3
Hi Mark
These are v2 of soc-core.c cleanup (maybe) step 3. These try to clenaup around kmalloc/kfree related code. Basically these do nothing from technical point of view. I added +1 extra patch as [00/14]
Kuninori Morimoto (14): ASoC: soc-core: move soc_free_pcm_runtime() ASoC: soc-core: merge soc_add_pcm_runtime() into soc_new_pcm_runtime() ASoC: soc-core: call list_del(&rtd->list) at soc_free_pcm_runtime() ASoC: soc-core: create rtd->codec_dais first ASoC: soc-core: merge soc_new_pcm_runtime() and soc_rtd_init() ASoC: soc-core: merge soc_free_pcm_runtime() and soc_rtd_free() ASoC: soc-core: tidyup soc_new_pcm_runtime() alloc order ASoC: soc-core: remove snd_soc_rtdcom_del_all() ASoC: soc-core: use devm_kzalloc() for rtd ASoC: soc-core: remove soc_remove_dai_links() ASoC: soc-core: add soc_setup_card_name() ASoC: soc-core: use devm_xxx for component related resource ASoC: soc-core: setup card->rtd_num at snd_soc_instantiate_card() ASoC: soc-ops: use snd_soc_card_get_kcontrol() at snd_soc_limit_volume()

We have soc_new_pcm_runtime() which allocs rtd and its related memory, and soc_add_pcm_runtime() which connects rtd to card.
But we don't need to separate these, we can alloc and connect rtd in the same time.
Current implementation is just makes code complex. This patch merges these into one.

"rtd" is handled by soc_xxx_pcm_runtime(), and "rtd->dev" is handled by soc_rtd_xxx().
There is no reason to separate these, and it makes code complex. We can free these in the same time.
Here soc_rtd_free() (A) which frees rtd->dev is called from soc_remove_link_dais() many times (1). Then, it is using dev_registered flags to avoid multi kfree() (2). This is no longer needed if we can merge these functions.

Current rtd, rtd->dev, rtd->codec_dais are created by normal kzalloc(), but we want to use devm_kzalloc() as much as possible.
Created rtd->dev is registered by device_register() at soc_new_pcm_runtime(), and it will be freed at soc_free_pcm_runtime() by device_unregister().
This means, if we can use devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais, all these are automatically freed via soc_free_pcm_runtime(). This patch uses devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais.

It is easy to read code if it is cleanly using paired function/naming, like start <-> stop, register <-> unregister, etc, etc. But, current ALSA SoC code is very random, unbalance, not paired, etc. It is easy to create bug at the such code, and it will be difficult to debug.
soc_cleanup_card_resources() (a) which is paired function of snd_soc_instantiate_card() (A) is calling soc_remove_dai_links() (*) to remove card related resources, but it is breaking add/remove balance (B)(b)(C)(c)(D)(d), in other words these should be called from soc_cleanup_card_resources() (a) from balance point of view.
More headacke is that it is using original removing method for dai_link even though we already have snd_soc_remove_dai_link() which is the function for it (d).
This patch removes snd_soc_remove_dai_links() and balance up code.

dai / component related resources are created when component is registered, and it will be freed when component was unregistered. These resources are not re-used after that. This means, we can use devm_xxx for dai / component, without thinking about kfree(). This patch uses devm_xxx for these.

card->rtd_num is used to count rtd. Initialize it at snd_soc_instantiate_card() is very natural and less confusion.
