[PATCH 00/17] ASoC: soc-dai: add snd_soc_dai_xxx()

[Kuninori Morimoto]

Hi Mark

We have soc-dai.c today. DAI related functions
should be implemented in it.
These patches are do it.

Kuninori Morimoto (17):
  ASoC: soc-dai: add soc_dai_err()
  ASoC: soc-dai: don't overwide dai->driver->ops
  ASoC: soc-dai: add snd_soc_pcm_dai_new()
  ASoC: soc-dai: add snd_soc_pcm_dai_prepare()
  ASoC: soc-dai: add snd_soc_pcm_dai_trigger()
  ASoC: soc-dai: add snd_soc_pcm_dai_bespoke_trigger()
  ASoC: soc-dai: add snd_soc_pcm_dai_probe()
  ASoC: soc-dai: add snd_soc_pcm_dai_remove()
  ASoC: soc-dai: add snd_soc_dai_compr_start()
  ASoC: soc-dai: add snd_soc_dai_compr_shutdown()
  ASoC: soc-dai: add snd_soc_dai_compr_trigger()
  ASoC: soc-dai: add snd_soc_dai_compr_set_params()
  ASoC: soc-dai: add snd_soc_dai_compr_get_params()
  ASoC: soc-dai: add snd_soc_dai_compr_ack()
  ASoC: soc-dai: add snd_soc_dai_compr_pointer()
  ASoC: soc-dai: add snd_soc_dai_compr_set_metadata()
  ASoC: soc-dai: add snd_soc_dai_compr_get_metadata()

[PATCH 01/17] ASoC: soc-dai: add soc_dai_err()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

At soc-dai.c, it is good idea to indicate error function and
its component name if there was error.
This patch adds soc_dai_err() for it.

the code below adds soc_dai_ret(), is this a typo?

Oops, It is typo.
The original code was _err, and I updated it to _ret

Mark
Do I need to post v3 patch ?

Thank you for your help !!

[PATCH 02/17] ASoC: soc-dai: don't overwide dai->driver->ops

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current ASoC overwides dai->driver->ops if it was NULL.
But, it is not good idea, because dai->driver might be reused
when modprobe/rmmod or bind/unbind, etc.

This patch checks dai->driver->ops when use DAI callbacks,
and removes null_dai_ops from ASoC.

This is fine but it's not a correctness issue since we're always filling
the same value in - the big issue with putting stuff in structures is
when you end up using the same struct for two different different things
so you fill different values in.

I see.
But all my remaining patches are based on this patch,
and rebase without it seems very difficult.

So, I want to keep it.
v2 patchset still has it, but adds different git-log.

Thank you for your help !!

Right, like I say the change is fine - it was just a note about the
changelog.

[PATCH 03/17] ASoC: soc-dai: add snd_soc_pcm_dai_new()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

We have 2 type of component functions
snd_soc_dai_xxx()     is focusing to dai itself,
snd_soc_pcm_dai_xxx() is focusing to rtd related dai.

Now we can update soc_dai_pcm_new() to
snd_soc_pcm_dai_new(). This patch do it.

I see the original code doesnt check the return value. But I think we
should here, no?

Yes, indeed.
But it is shutdown function.
Just reporting dev_err() is enough I think.
What do you think ?

Thank you for your help !!

Yes, but now that you mention it, maybe we dont even need to report it.
The actual driver shutdown op would probably report it anyway.
