[RFC][PATCH v4 0/2] ASoC: core: use Complete rebind cards by default for all users

[Kuninori Morimoto]

Hi Mark, Cezary

Topology is using (A), but its paired (B) might not be called.
Because of it, it will be hungup, because soc_cleanup_card_resources()
will access to devm_kzalloc():ed link (= rtd->link) which was already
lost in that timing.
    
	(A) snd_soc_add_pcm_runtimes()
	(B) snd_soc_remove_pcm_runtime()
    
To solve this issue, it uses devres_alloc() and call (B) in topology.

But I can't test it. It needs Acked-by / Tested-by from Cezary.
I added [RFC]

v3 -> v4
	- call topology snd_soc_remove_pcm_runtime()
	- rebind() function will handle all cards by itself.

v2 -> v3
	- separate bind/unbind/rebind and unbind list handling
	- tidyup git-log and Subject

v1 -> v2
	- tidyup handling of client_mutex

[RFC][PATCH v4 1/2] ASoC: topology: make sure to call snd_soc_remove_pcm_runtime()

[Kuninori Morimoto]

soc-topology will call (A), so it needs to call (B) when link was released.
Otherwise, soc_cleanup_card_resources() will access to devm_kzalloc():ed
link (= rtd->link) which was already lost in that timing.

	(A) snd_soc_add_pcm_runtimes()
	(B) snd_soc_remove_pcm_runtime()

To solve this issue, it uses devres_alloc() and call (B)

[RFC][PATCH v4 2/2] ASoC: core: use Complete rebind cards by default for all users

[Kuninori Morimoto]

commit a3375522bb5e2 ("ASoC: core: Complete support for card rebinding")
supports complete card rebinding, but it uses unbalanced pair functions
It added devm_snd_soc_bind_card() (= bind), but its inverse function is
snd_soc_unregister_card() (= unregister), and it adds new
devm_snd_soc_register_deferrable_card() (= register), but it doesn't have
inverse function (= merged with above inverse of bind function).

This feature is mainly used on Intel driver, but all driver can use it.
Let's use it on all drivers.

bin/unbind functions are soc-core.c local, so let's rename it.
It added new rebind function.
	snd_soc_bind_card()	-> soc_card_bind()
	snd_soc_unbind_card()	-> soc_card_unbind()
	snd_soc_rebind_card()	-> soc_card_rebind()

I've tested it out and results (KASAN) are very similar to the previous 
revisions.  Attaching exemplary dmesg for the exact same order of 
operations as last time.

In regard to technical part, I have to disagree with the approach taken 
in v4.  The goal behind the series: make the code implementing the 
re-binding feature easier to follow.  Here, the following are added:

- soc_tplg_remove_pcm()
- soc_tplg_link_release()
- struct tplg_link

There is soc_tplg_remove_link() already, I believe introducing 
soc_tplg_link_release(), an "unbalanced" function goes against the goal 
of the patch.  Internal struct is a heavy hitter, I'd argue it alone 
defeats the purpose of the patch.

The delta of this series 1) when compared against the proposition of 
mine 2) - attachment found in v3 review:

1) 5 files changed, 71 insertions(+), 68 deletions(-)
2) 3 files changed, 17 insertions(+), 57 deletions(-)

Perhaps we can achieve the goal in multiple steps.  Simplify the code 
implementing the feature by merging 2) and work from there if you 
believe the readability still isn't where it should be.

Side note: leaving the current function names as is would make it easier 
to review the series. Right now, after 'git am' I have to rename 
everything myself and amend the changes to even begin accessing the 
actual impact of the code.


Kind regards,
Czarek
