mtd: rawnand: sh_flctl: Use proper enum for flctl_dma_fifo0_transfer
[ Upstream commit e2bfa4ca23d9b5a7bdfcf21319fad9b59e38a05c ] Clang warns when one enumerated type is converted implicitly to another: drivers/mtd/nand/raw/sh_flctl.c:483:46: warning: implicit conversion from enumeration type 'enum dma_transfer_direction' to different enumeration type 'enum dma_data_direction' [-Wenum-conversion] flctl_dma_fifo0_transfer(flctl, buf, rlen, DMA_DEV_TO_MEM) > 0) ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~ drivers/mtd/nand/raw/sh_flctl.c:542:46: warning: implicit conversion from enumeration type 'enum dma_transfer_direction' to different enumeration type 'enum dma_data_direction' [-Wenum-conversion] flctl_dma_fifo0_transfer(flctl, buf, rlen, DMA_MEM_TO_DEV) > 0) ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~ 2 warnings generated. Use the proper enums from dma_data_direction to satisfy Clang. DMA_MEM_TO_DEV = DMA_TO_DEVICE = 1 DMA_DEV_TO_MEM = DMA_FROM_DEVICE = 2 Reported-by: Nick Desaulniers <ndesaulniers@google.com> Signed-off-by: Nathan Chancellor <natechancellor@gmail.com> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
