spi/spi-ep93xx.c: use dma_transfer_direction instead of dma_data_dire…
…ction A new enum indicating the dma channel direction was introduced by: commit 49920bc dmaengine: add new enum dma_transfer_direction The following commit changed spi-ep93xx to use the new enum: commit a485df4 spi, serial: move to dma_transfer_direction In doing so a sparse warning was introduced: warning: mixing different enum types int enum dma_data_direction versus int enum dma_transfer_direction This is produced because the 'dir' passed in ep93xx_spi_dma_prepare is an enum dma_data_direction and is being used to set the dma_slave_config 'direction' which is now an enum dma_transfer_direction. Fix this by converting spi-ep93xx to use the new enum type in all places.
