linux-yocto/drivers/dma/TODO
Andy Shevchenko dd8ecfcac6 dmaengine: dw: don't perform DMA when dmaengine_submit is called 
Accordingly to discussion [1] and followed up documentation the DMA controller
driver shouldn't start any DMA operations when dmaengine_submit() is called.

This patch fixes the workflow in dw_dmac driver to follow the documentation.
