That's what you said last time :)
So, how about this, please draw up a specific plan for how you are going
to get this code out of drivers/staging/ I want to see the steps
involved, who is going to be doing the work, and who you are going to
have to get to agree with your changes to make it happen.
After that, then I'll consider taking stuff like this, as it's "obvious"
that this is the way forward. Right now I have no idea at all if this
is something new that you are adding, or if it's something that really
is helping to get the code merged.
Yeah, a plan, I know it goes against normal kernel development
procedures, but hey, we're in our early 20's now, it's about time we
started getting responsible.
