Additionally, I've included: * A fix for a plx-dma issue that was reported on the list[1] a few weeks ago. * A potential issue I noticed while reviewing the code where pointers need to be set to NULL. These fixes are all valid and independent of the work I was doing so I've sent them as their own submission. I'm still working on the rest of the feedback Sashiko gave me on that submission.
