fsldma: major cleanups and fixes
Fix locking. Use two queues in the driver, one for pending transacions, and one for transactions which are actually running on the hardware. Call dma_run_dependencies() on descriptor cleanup so that the async_tx API works correctly. There are a number of places throughout the code where lists of descriptors are freed in a loop. Create functions to handle this, and use them instead of open-coding the loop each time. Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
