This is a decision above my pay grade. Ok, that's a decision you are going to have to push upward on, as we really can't take this without a working, open, userspace. Especially given the copyright owner of this code, that would be just crazy and foolish to not have open userspace code as well. Firmware would also be wonderful as well, go poke your lawyers about derivative work issues and the like for fun conversations :) So without that changed, I'm not going to take this, and push to object that anyone else take this. I'm not going to be able to review any of this code anymore until that changes, sorry. thanks, greg k-h
