commit33949eb501("ASoC: samsung: arndale_rt5631: don't select unnecessary Platform") Current ALSA SoC avoid to add duplicate component to rtd, and this driver was selecting CPU component as Platform component. Thus, above patch removed Platform settings from this driver, because it assumed these are same component. But, some CPU driver is using generic DMAEngine, in such case, both CPU component and Platform component will have same of_node/name. In other words, there are some components which are different but have same of_node/name. In such case, Card driver definitely need to select Platform even though it is same as CPU. It is depends on CPU driver, but is difficult to know it from Card driver. This patch reverts above patch.
