Greg did not yell at me (yet) so I guess I'm doing OK :)

I think we have enough maintainers in this subsystem:

  Andreas - Apple hardware
  Michael and me - Intel
  Yehezkel - Microsoft

But I think we can make you a dedicated reviewer. This should make sure
you get to review all the patches touching this subsystem.

However, first I would like to get confirmation from Andreas that he
approves this.

I also would like that anyone submitting patches to this subsystem do
not get bad feelings during the review but instead possible issues and
improvement suggestions are written in such way that the submitter feels
his work is valued (even if not always correct).

This is especially important when a random Intel (well, or Apple)
engineer submits a patch, say fixing a typo in a comment of some data
structure. There is no point starting to demand that the specific
register meaning needs to be disclosed. I've said this before but I or
any other Intel engineer do not have any power over when the spec is
released or any other related matter (like disclosing registers) and I
really don't want that every single patch review starts with demanding
people to disclose something extra. After all they are just trying to
improve the driver which is good for Linux.

If Andreas approves this, please send a patch adding you as a reviewer
and I'll apply it. Just please write the changelog in good will without
any personal frustration as those will be recorded forever in the kernel
history and you never know in future who you are working for.

From my point of view, I welcome you on board as good reviewer :)
