From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Current rtd, rtd->dev, rtd->codec_dais are created by normal kzalloc(), but we want to use devm_kzalloc() as much as possible. Created rtd->dev is registered by device_register() at soc_new_pcm_runtime(), and it will be freed at soc_free_pcm_runtime() by device_unregister(). This means, if we can use devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais, all these are automatically freed via soc_free_pcm_runtime(). This patch uses devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais.
