Please use it instead of bool. Thank you for your help !! Best regards --- Kuninori Morimoto

dpcm_end_walk_at_be() stops the graph walk when first BE is found for the given FE component. In a component model we may want to connect multiple DAIs from different components. A new flag is introduced in 'snd_soc_card', which when set allows DAI/component chaining. Later PCM operations can be called for all these listed components for a valid DAPM path.
