This is starting to become a recurring problem is it not?
Have you considered the option to start to send your pull
requests to Linus (Torvalds) directly?
I suppose the current scheme is used because IIO changes
can affect drivers/staging/ but at this point that thing is
so much smaller than the stuff in drivers/iio proper that
I start to question if it's worth it.
Unless you really like to base your work on Gregs tree for
some reason or other, that is.
Yours,
Linus Walleij
