Wolfram Sang 6e9c5c8ef2 dmaengine: sh: rz-dmac: handle configs where one address is zero ... Configs like the ones coming from the MMC subsystem will have either 'src' or 'dst' zeroed, resulting in an unknown bus width. This will bail out on the RZ DMA driver because of the sanity check for a valid bus width. Reorder the code, so that the check will only be applied when the corresponding address is non-zero.
