Can you use -next plus the posted patches please in case there's
something been misplaced, it'll help if we're working from the same code

Can you please send a patch for that if you find it's needed?  Like I
said in reply to your earlier mail it looks like this doesn't work
anyway so mainline ought to be fixed.

So this is 16 bit stereo or something, and did it work beforehand?  Like
I say I suspect the DMA is ending up being configured with the wrong
transfer size, can you check what actually happens there please - what's
different about the configuration that the DMA controller gets?  I don't
have any Exynos systems with mainline audio support so I can't test
anything myself.
