Current error handling on snd_soc_dapm_add_route() has some wastes. It indicates *own* error message *only* for sink or source, and return error directly at (A). OTOH, it has similar error message at (B) which indicates *both* sink/source.

And more, (A) is using dev_err(), (B) is using dev_warn(). (B) is caring prefix, but (A) is not.

(X) int snd_soc_dapm_add_route(...) { ... if (wsource == NULL) { (A) dev_err(...); return -ENODEV; } if (wsink == NULL) { (A) dev_err(...); return -ENODEV; }

...

ret = snd_soc_dapm_add_path(...); if (ret) (B) goto err;

return 0; err: (B) dev_warn(...); return ret; }

Above snd_soc_dapm_add_route() (= X) is called from snd_soc_dapm_add_routes() (= Y). (X) will indicate error message by itself, but (Y) will indicate own error message at (C). (C) is duplicated.

(Y) int snd_soc_dapm_add_routes(...) { ... for (...) { (X) int r = snd_soc_dapm_add_route(...); if (r < 0) { (C) dev_err(...); ret = r; } ... } ... }

This patch (1) merges these error message (= A,B) into one, (2) use dev_err(), (3) remove duplicate error message (= C) from snd_soc_dapm_add_routes().

By this patch, it will indicate error message like this.

- error message with prefix - not found widget will have "(*)" mark - it indicates [control] if exists.

ex) [if no sink with control]

ASoC: Failed to add route SOURCE -> [CTRL] -> SINK(*)

[if no source without control]

ASoC: Failed to add route SOURCE(*) -> SINK

Currently snd_soc_dapm_free_widget() is assuming input parameter is non NULL. Thus, caller need to care about it. This patch care it at snd_soc_dapm_free_widget().

It should be more simple, but the code is unnecessarily complicated, and difficult to read/understand. This patch merge these into one.

snd_soc_dapm_new_dai() setups local variable "template" at (X) and (Y), which is used at (Z). But these are difficult to read.

static struct snd_soc_dapm_widget * snd_soc_dapm_new_dai() { ...

^ template.reg = ... | template.id = ... (X) template.name = ... | template.event = ... | template.event_flags = ... v template.kcontrol_news = ...

if (rtd->dai_link->num_params > 1) { ... ^ template.num_kcontrols = ... (Y) template.kcontrol_news = ... v ... }

... (Z) w = snd_soc_dapm_new_control_unlocked(..., &template);

}

And this function has error message, but not for all cases. This patch (1) setups "template" in one place, and indicate error message for all cases. This patch cleanup the code, but nothing changed for meaning.

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

Current soc-pcm.c is coping fe hw_param to dpcm->hw_param (A), fixup it (B), and copy it to be (C).

int dpcm_be_dai_hw_params(...) { ... for_each_dpcm_be(fe, stream, dpcm) { ... /* copy params for each dpcm */ (A) memcpy(&dpcm->hw_params, &fe->dpcm[stream].hw_params, ...) ;

/* perform any hw_params fixups */ (B) ret = snd_soc_link_be_hw_params_fixup(be, &dpcm->hw_params); ...

/* copy the fixed-up hw params for BE dai */ (C) memcpy(&be->dpcm[stream].hw_params, &dpcm->hw_params, ...); ... } ... }

But here, (1) it is coping hw_params without caring stream (Playback/Capture), (2) we can get same value from be. We don't need to have dpcm->hw_params. This patch removes it.
