5fa422c ("dmaengine: move drivers/of/dma.c -> drivers/dma/of-dma.c") moved OF base DMAEngine code to of-dma.c, then it based on CONFIG_DMA_OF. But, OF base DMAEngine API on of_dma.h still based on CONFIG_OF now. So, current kernel can't find OF base DMAEngine API if .config has CONFIG_OF, but not have CONFIG_DMA_OF. This patch tidyup it.
I did a quick build with arm config, but didn't see any failures. But still am worried about random config and other builds may find.
So I think it would be safer to merge this patch after merge window so that we have ample time to fix any issue
