spi: core: Pass correct device to dma_map_sg()
According to Documentation/dmaengine.txt, scatterlists must be mapped using the DMA struct device. However, "dma_chan.dev->device" is the sysfs class device's device. Use "dma_chan.device->dev" instead, which is the real DMA device's device. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Mark Brown <broonie@linaro.org>
