Hi Sameer
PCM devices are created for dai links with 'no-pcm' flag as '0'. Such DAI links have CPU component which implement pcm_construct() and pcm_destruct() callbacks. Based on this, current patch exposes a helper function to identify such components and populate 'no_pcm' flag for DPCM DAI link. (snip) +bool soc_component_is_pcm(struct snd_soc_dai_link_component *dlc) +{ + struct snd_soc_component *component; + struct snd_soc_dai *dai; + + for_each_component(component) { + if (!component->driver) + continue; + + for_each_component_dais(component, dai) { + if (!dai->name || !dlc->dai_name) + continue; + + if (strcmp(dai->name, dlc->dai_name)) + continue;
We can/should NULL poinster check for "dlc->dai_name" on top of this function instead of inside loop ? And then, we can remove "dai->name" check because next strcmp() automatically fail if dai->name was NULL. Thank you for your help !! Best regards --- Kuninori Morimoto
