Subject: dmaengine: timb_dma: Use proper enum in td_prep_slave_sg
Date: Tue, 11 Sep 2018 16:20:25 -0700	[thread overview]
Message-ID: <20180911232025.4909-1-natechancellor@gmail.com> (raw)

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]

                                        ^~~~~~~~~~~~~~
