Yep... my mistake! I had rebased my patches on top on -mm tree just top
get those patches that I mentioned in [2], but then I rebased back to
master, which had some conflicts...

So, now I just pushed my changes on top on [2], which you can access
here[3]. I also included the revert of the code that converted 8250 to
NBCON, which is easier to test it using qemu, as I presented on the
cover-leter.

Thanks a lot for reviewing and testing the patchset!
