commit e60a582bcde01158a64ff948fb799f21f5d31a11 upstream.
clang points out several instances of mismatched types in this drivers, all coming from a single declaration:
drivers/mmc/host/pxamci.c:193:15: error: implicit conversion from enumeration type 'enum dma_transfer_direction' to different enumeration type 'enum dma_data_direction' [-Werror,-Wenum-conversion] direction = DMA_DEV_TO_MEM; ~ ^~~~~~~~~~~~~~ drivers/mmc/host/pxamci.c:212:62: error: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Werror,-Wenum-conversion] tx = dmaengine_prep_slave_sg(chan, data->sg, host->dma_len, direction,
The behavior is correct, so this must be a simply typo from dma_data_direction and dma_transfer_direction being similarly named types with a similar purpose.
