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.
