The commit dfa3cbb8(ASoC: mediatek: modify MT2701 AFE driver to adapt mfd device) leads to the following static checker warning: sound/soc/mediatek/mt2701/mt2701-afe-pcm.c:1535 mt2701_afe_pcm_dev_probe() error: double free of 'component' This patch fixes that and adds a helper mt2701_afe_add_component() to setup component.
