Speaking about that. I would gladly help out to host a git tree to
collect patches that you have acked. In this way, we can, for example,
get the patches pre-tested in linux next before we send the
pull-request.

If you think sounds like a good idea, just tell me so I can prepare a
tree for the next release cycle...

Kind regards
