From: Fabio Estevam <fabio.estevam@xxxxxxx> After the conversion from platform to component the following warnings are seen: fsl-ssi-dai 2028000.ssi: ASoC: Failed to create component debugfs directory fsl-spdif-dai 2004000.spdif: ASoC: Failed to createcomponent debugfs directory As explained by Mark Brown: "It's a legit warning - we shouldn't really be creating two components for the same device. However this is a bit of a corner case as it's the dmaengine platform driver which is kind of a virtual device, it's not really the device that we use with DMA that's being represented but rather the link between that and the DMA controller." Disambiguate the DMA component name by adding a "dma" debugfs_prefix entry.
