[PATCH AUTOSEL 4.19 046/209] dmaengine: timb_dma: Use proper enum in td_prep_slave_sg

[Sasha Levin]

From: Nathan Chancellor <natechancellor@xxxxxxxxx>

[ 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);
                                        ^~~~~~~~~~~~~~
