The patch "ASoC: Prevent components from being bound to multiple cards" adds check to prevent multiple cards from using the same component. However, snd_soc_register_platform() or snd_soc_register_codec() will also create components, and sharing the same platform by multiple cards is then refused. This happens with a platform having multiple independent DAIs that share the same DMA controller.
Relax the condition by checking component->registered_as_component, which is only true in case of snd_soc_register_component() and will be false for components created by snd_soc_register_platform() or snd_soc_register_codec().
