| Subject: dmaengine: timb_dma: Use proper enum in td_prep_slave_sg |
| |
| From: Nathan Chancellor <natechancellor@gmail.com> |

| [ Upstream commit 5e621f5d538985f010035c6f3e28c22829d36db1 ] |
| |
| Clang warns when implicitly converting from one enumerated type to |
| another. Avoid this by using the equivalent value from the expected |
| type. |
| |
| drivers/dma/timb_dma.c:548:27: warning: implicit conversion from |
| enumeration type 'enum dma_transfer_direction' to different enumeration |
| type 'enum dma_data_direction' [-Wenum-conversion] |
| td_desc->desc_list_len, DMA_MEM_TO_DEV); |
| ^~~~~~~~~~~~~~ |
