dmaengine: Mark the struct dma_slave_config direction field deprecated
The direction passed to the device_prep_slave_sg, device_prep_dma_cyclic or device_prep_interleaved_dma (through struct dma_interleaved_template) should be used instead. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
