dmaengine: add DMA_TRANS_NONE to dma_transfer_direction
Before dma_transfer_direction was introduced to replace dma_data_direction, some dmaengine device uses DMA_NONE of dma_data_direction for some talk with its client drivers. The mxs-dma and its clients mxs-mmc and gpmi-nand are such case. This patch adds DMA_TRANS_NONE to dma_transfer_direction and migrate the DMA_NONE use in mxs-dma to it. It also fixes the compile warning below. CC drivers/dma/mxs-dma.o drivers/dma/mxs-dma.c: In function ‘mxs_dma_prep_slave_sg’: drivers/dma/mxs-dma.c:420:16: warning: comparison between ‘enum dma_transfer_direction’ and ‘enum dma_data_direction’ Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
