There's a patch in -next that lets the generic dmaengine code figure out some settings from the dmacontroller rather than requiring the driver to explicitly provide configuration - it's "ASoC: dmaengine-pcm: Provide default config". Please update your driver to use this, or let's work out what it doesn't do any try to fix it.

I couldn't find the patch in the next and other trees. Does this patch has been submitted to the -next tree ? Or could you tell me how to find the patch please?

Thanks very much.
