That has been my long term plan, but I didn't know when I would get to
that point. There's always somethings that come up and I didn't know if
I would get the necessary reviews now that many are on summer vacation.
I have now gotten the necessary ack/r-b to move on and I found a
solution to the BACKLIGHT dependency problem I had, so this has
progressed faster than I could hope for.

I can add a patch that does that.
