This patchset fixes a couple of problems with stopping and restarting an ioat DMA device. Following the three fixes, a series of improvements are made to the dmadev unit tests to properly validate that dmadevs work correctly as they are started and stopped, and ensure that no other or future drivers will suffer from issues.
