The cover letter still doesn't state what this series applies to, or
what its dependencies are for testing, even though it was requested in
earlier reviews[1].  I discovered (again) by trial and error it applies
to current linux-next.  I also discovered (as was earlier discussed[2])
that it still does not resume using current upstream code, and those
dependencies are not described here either.  These are the kinds of
things that are crucial in a cover letter in order to help reviewers and
testers not have to spend time digging through the archives trying to
remember from the previous round of reviews. 

Please, please list the out-of-tree dependencies, and how to test,
including how you tested it, and on what hardware.

Speaking of earlier reviews, I've noticed that after reviewing this
series multiple times, you never respond to questions and/or comments.
Two-way communication is important when collaborating on getting complex
code this upstream, so please take some time to acknowledge the comments
of reviewers and engage in discussion when questions are asked.  Even if
it's as simple as "OK, I'll fix it in the next version", that helps
reviewers know that they're not wasting their time.
