Nathan Chancellor ed896ddfae mtd: rawnand: sh_flctl: Use proper enum for flctl_dma_fifo0_transfer
[ Upstream commit e2bfa4ca23 ]

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
