[ Upstream commit 9524d6b265f9b2b9a61fceb2ee2ce1c2a83e39ca ]
Clang warns when implicitly converting from one enumerated type to another. Avoid this by using the equivalent value from the expected type.
In file included from drivers/dma/ep93xx_dma.c:30: ./include/linux/platform_data/dma-ep93xx.h:88:10: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] return DMA_NONE; ~~~~~~ ^~~~~~~~ 1 warning generated.
