spi: sh-msiof: Use correct enum for DMA transfer direction
Use enum dma_transfer_direction as required by dmaengine_prep_slave_sg() instead of enum dma_data_direction. This won't change behavior in practice as the enum values are equivalent. This fixes two warnings when building with clang: drivers/spi/spi-sh-msiof.c:755:27: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] rx->sgl, rx->nents, DMA_FROM_DEVICE, ^~~~~~~~~~~~~~~ drivers/spi/spi-sh-msiof.c:772:27: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] tx->sgl, tx->nents, DMA_TO_DEVICE, ^~~~~~~~~~~~~ Based on commit 768d59f5d0139a6f ("spi: rspi: use correct enum for DMA transfer direction").
