spi: pic32: Use proper enum in dmaengine_prep_slave_rg
[ Upstream commit 8cfde7847d5ed0bb77bace41519572963e43cd17 ]
Clang warns when one enumerated type is converted implicitly to another:
drivers/spi/spi-pic32.c:323:8: warning: implicit conversion from
enumeration type 'enum dma_data_direction' to different enumeration type
'enum dma_transfer_direction' [-Wenum-conversion]
DMA_FROM_DEVICE,
^~~~~~~~~~~~~~~
drivers/spi/spi-pic32.c:333:8: warning: implicit conversion from
enumeration type 'enum dma_data_direction' to different enumeration type
'enum dma_transfer_direction' [-Wenum-conversion]
DMA_TO_DEVICE,
^~~~~~~~~~~~~
2 warnings generated.
Use the proper enums from dma_transfer_direction (DMA_FROM_DEVICE =
DMA_DEV_TO_MEM = 2, DMA_TO_DEVICE = DMA_MEM_TO_DEV = 1) to satify Clang.
