Hello,

In dw_dmac.c driver, dwc_descriptor_complete() routine, following is
mentioned before calling callback:

	/*
	 * The API requires that no submissions are done from a
	 * callback, so we don't need to drop the lock here
	 */
	if (callback)
		callback(param);

Does this hold true for dmaengine??
