dear programmer:

        I bought a i.MX6Q board, Android version:4.4.2, Kernel version:3.0.35.

        Now, i test the DMA function and i found a question.

        After i finish the DMA init, i start DMA transfer. But i found the function(static void imxdma_issue_pending(struct dma_chan *chan)) is not be finished. It is a null function!

        How can i do it?

        Thank you.
