    Clang warns when one enumerated type is implicitly converted to another.

    enumeration type 'enum dma_data_direction' to different enumeration type

    Use the equivalent valued enums from the expected type so that Clang no
    longer warns about a conversion.
    
    DMA_TO_DEVICE = DMA_MEM_TO_DEV = 1
    DMA_FROM_DEVICE = DMA_DEV_TO_MEM = 2
