It should be against -hg or linux-next tree, otherwise, I can't send it upstream.
If you just want to send a patch for people to test, please mark it as RFC, otherwise
I'll assume that you're sending a patch for upstream.

Since there are more people working on this driver, the better is to add what you
have there, to avoid people to do a similar work.

Ah, ok :)

Ok. While it is still at -staging, we can keep the proprietary ioctls, but they
need to be removed before moving to the right place.

Cheers,
