spi: rspi: 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-rspi.c:538:26: 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-rspi.c:558:26: 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,
^~~~~~~~~~~~~
