From: Martin Oliveira <martin.oliveira@xxxxxxxxxxxxx> The .map_sg() op now expects an error code instead of zero on failure. vdma_alloc() may fail for different reasons, but since it only supports indicating an error via a return of DMA_MAPPING_ERROR, we coalesce the different reasons into -EINVAL.
