Original snd_soc_dai_compress_new() return was below.
Here, snd_soc_dai_compress_new() will return -ENOTSUPP if driver doesn't
support .compress_new() callback. Will return handled value if
callback was supported.
ret = snd_soc_dai_compress_new(...);
if (ret != -ENOTSUPP) {
if (ret < 0)
dev_err(...);
return ret;
}
So this means, it will return here anyway if driver supports
the callback even though it was success/failed.
This was updated by commit 62462e018220 ("ASoC: don't indicate error
message for snd_soc_[pcm_]dai_xxx()") like below
ret = snd_soc_dai_compress_new(...);
if (ret != -ENOTSUPP)
return ret;
It still return here if driver supports callback.
But commit dd9f9cc1e6b9 ("ASoC: core: Do not call link_exit() on
uninitialized rtd objects") updated to like below to call
snd_soc_link_exit() if error case.
ret = snd_soc_dai_compress_new(...);
if (ret != -ENOTSUPP)
=> goto err;
But this looks like error, but is not.
This is very confusable. Let's tidyup them.
Fixes: dd9f9cc1e6b9 ("ASoC: core: Do not call link_exit() on uninitialized rtd objects")

struct snd_soc_card will be capsuled soon, its member will not be
able to access from non soc-card.c.
It has too many local function dependencies.
This patch uses temporary funciton define at soc-internal.h. It will be
removed all funciton were moved.
It renames function name

struct snd_soc_card will be capsuled soon, its member will not be
able to access from non soc-card.c.
It has too many local function dependencies.
This patch uses temporary funciton define at soc-internal.h. It will be
removed all funciton were moved.
It renames function name
- soc_unbind_aux_dev()
- soc_bind_aux_dev()
+ snd_soc_card_aux_unbind()
+ snd_soc_card_aux_bind()
Below function is used on above functions. Add them at soc-internal.h
Align with existing snd_soc_find_dai()
- soc_find_component()
+ snd_soc_find_component()

From: Kuninori Morimoto @ 2026-10-28 3:03 UTC (permalink / raw)
To: Mark Brown; +Cc: linux-sound
struct snd_soc_card will be capsuled soon, its member will not be
able to access from non soc-card.c.
It has too many local function dependencies.
This patch uses temporary funciton define at soc-internal.h. It will be
removed all funciton were moved.
It renames function name
- call_soc_bind_card()
- snd_soc_bind_card()
- snd_soc_unbind_card()
+ snd_soc_card_bind_call()
+ snd_soc_card_bind()
+ snd_soc_card_unbind()
Below function is used on above functions. Add them at soc-internal.h
+ snd_soc_flush_all_delayed_work()

There were too many local function dependencies to move Card related
function from soc-core.c to soc-card.c.
Now, all functions were moved, let's remove temporary funciton defines.

A bit irrelevant to capsuling, but I think it would make more sense for
the list to be called unbound_card_list. It would make this part more
understandable:
int snd_soc_component_register(struct snd_soc_component *component,
struct snd_soc_dai_driver *dai_drv,
int num_dai)
{
struct snd_soc_card *card, *c;
...
/* Alvin's comment: retry binding any unbound cards in case this
* component completes them
*/
list_for_each_entry_safe(card, c, &unbind_card_list, list)
snd_soc_card_bind_call(card);
...
}
But feel free to ignore :)
Kind regards,
Alvin

I'm doing it mainly for global functions.
Not so much for local/static functions, for now.
Thank you for your help !!
