Dirk Behme 5db50e4f36 dmaengine: sh: rcar-dmac: With cyclic DMA residue 0 is valid ... commit 907bd68a2e upstream. Having a cyclic DMA, a residue 0 is not an indication of a completed DMA. In case of cyclic DMA make sure that dma_set_residue() is called and with this a residue of 0 is forwarded correctly to the caller.
