ASoC: soc-component: add mark for snd_soc_link_compr_startup/shutdown()
soc_compr_open() does rollback when failed (A),
but, it is almost same as soc_compr_free().
static int soc_compr_open(xxx)
{
...
if (ret < 0)
goto xxx_err;
...
return 0;
^ machine_err:
| ...
| out:
(A) ...
| pm_err:
| ...
v return ret;
}
The difference is
soc_compr_free() is for all dai/component/substream,
rollback is for succeeded part only.
This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_compr_free() and rollback.
1) snd_soc_dai_compr_startup/shutdown()
2) snd_soc_component_compr_open/free()
=> 3) snd_soc_link_compr_startup/shutdown()
This patch is for 3) snd_soc_link_compr_startup/shutdown()
and adds new cstream mark.
It will mark cstream when startup() was suceeded.
If rollback happen *after* that, it will check rollback flag
and marked cstream.
It cares *previous* startup() only now,
but we might want to check *whole* marked cstream in the future.
This patch is using macro so that it can be easily adjust to it.
