The problem the dependent patch is in linux-next and not in arch trees yet. That is why I am trying it get this through linux-next and/or dma-debug tree. I am open to suggestions on what is the best route.
linux-next commit-id is:
commit 6c9c6d6301287e369a754d628230fa6e50cdb74b
I have another one that I sent to linux-next that fixes the dependency on get_dma_ops():
