ata: ep93xx: Use proper enums for directions
Clang warns when one enumerated type is implicitly converted to another. drivers/ata/pata_ep93xx.c:662:36: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] drv_data->dma_rx_data.direction = DMA_FROM_DEVICE; ~ ^~~~~~~~~~~~~~~ drivers/ata/pata_ep93xx.c:670:36: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] drv_data->dma_tx_data.direction = DMA_TO_DEVICE; ~ ^~~~~~~~~~~~~ drivers/ata/pata_ep93xx.c:681:19: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] conf.direction = DMA_FROM_DEVICE; ~ ^~~~~~~~~~~~~~~ drivers/ata/pata_ep93xx.c:692:19: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] conf.direction = DMA_TO_DEVICE; ~ ^~~~~~~~~~~~~ Use the equivalent valued enums from the expected type so that Clang no longer warns about a conversion.
