Client D/D normally uses 'enum dma_slave_buswidth' type.
However, dmaengine driver cannot guarantee all client D/D uses it.
See below your spi driver. Thus, the dmaengine driver check it correctly.

+#if defined(CONFIG_DMADEV_PL330)
+                       memset(&slave_config, 0, sizeof(slave_config));
+                       slave_config.direction = DMA_TO_DEVICE;
+                       slave_config.src_addr = xfer->tx_dma;
+                       slave_config.dst_addr =
+                               sdd->sfr_start + S3C64XX_SPI_TX_DATA;
+                       slave_config.dst_addr_width = sdd->cur_bpw / 8;
+                       dmaengine_slave_config(sdd->tx_chan, &slave_config);
