Hi ASoC Cc Lars-Peter
I have noticed that DAPM source vs sink are strange.
ASoC had used source/sink or input/output before, but it was exchanged by this patch
a3423b02cf745c1418f1f199646c450d6fc9ca4e ("ASoC: dapm: Consolidate input and output path handling")
I think source/sink pair are converted to SND_SOC_DAPM_DIR_IN/OUT by this patch.
source <=> IN sink <=> OUT
But, its for_each are inverted
#define snd_soc_dapm_widget_for_each_sink_path(w, p) \ snd_soc_dapm_widget_for_each_path(w, SND_SOC_DAPM_DIR_IN, p)
#define snd_soc_dapm_widget_for_each_source_path(w, p) \ snd_soc_dapm_widget_for_each_path(w, SND_SOC_DAPM_DIR_OUT, p)
I have thought this for_each is for special handling, but, the original was sink is for sink, source is for source after all.
#define snd_soc_dapm_widget_for_each_sink_path(w, p) \ list_for_each_entry(p, &w->sinks, list_source)
#define snd_soc_dapm_widget_for_each_source_path(w, p) \ list_for_each_entry(p, &w->sources, list_sink)
So, I guess current for_each is wrong, but I'm not 100% sure
#define snd_soc_dapm_widget_for_each_sink_path(w, p) \ - snd_soc_dapm_widget_for_each_path(w, SND_SOC_DAPM_DIR_IN, p) + snd_soc_dapm_widget_for_each_path(w, SND_SOC_DAPM_DIR_OUT, p)
#define snd_soc_dapm_widget_for_each_source_path(w, p) \ - snd_soc_dapm_widget_for_each_path(w, SND_SOC_DAPM_DIR_OUT, p) + snd_soc_dapm_widget_for_each_path(w, SND_SOC_DAPM_DIR_IN, p)
I'm happy to create patch if I could get your ack.
Thank you for your help !!
