This change looks correct and is certainly the simplest solution if you want to
get it into v4.8, but generally speaking, I think it would be nicer to combine
it with the initialization of the fields:
struct dma_slave_config cfg = {
.src_addr = host->mapbase + OMAP_HSMMC_DATA;
.dst_addr = host->mapbase + OMAP_HSMMC_DATA;
.src_addr_width = DMA_SLAVE_BUSWIDTH_4_BYTES;
.dst_addr_width = DMA_SLAVE_BUSWIDTH_4_BYTES;
.src_maxburst = data->blksz / 4;
.dst_maxburst = data->blksz / 4;
};
