Clang warns when implicitly converting from one enumerated type to another. Avoid this by using the equivalent value from the expected type.
drivers/dma/timb_dma.c:548:27: warning: implicit conversion from enumeration type 'enum dma_transfer_direction' to different enumeration type 'enum dma_data_direction' [-Wenum-conversion] td_desc->desc_list_len, DMA_MEM_TO_DEV); ^~~~~~~~~~~~~~ 1 warning generated.
