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

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

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

  ASoC: topology: make sure to call snd_soc_remove_pcm_runtime()
  ASoC: core: use Complete rebind cards by default for all users
