crypto: ux500 - Use proper enum in hash_set_dma_transfer
[ Upstream commit 5ac93f808338f4dd465402e91869702eb87db241 ] Clang warns when one enumerated type is implicitly converted to another: drivers/crypto/ux500/hash/hash_core.c:169:4: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] direction, DMA_CTRL_ACK | DMA_PREP_INTERRUPT); ^~~~~~~~~ 1 warning generated. dmaengine_prep_slave_sg expects an enum from dma_transfer_direction. We know that the only direction supported by this function is DMA_TO_DEVICE because of the check at the top of this function so we can just use the equivalent value from dma_transfer_direction. DMA_TO_DEVICE = DMA_MEM_TO_DEV = 1 Signed-off-by: Nathan Chancellor <natechancellor@gmail.com> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Sasha Levin <sashal@kernel.org>
