I'd suggest to move to sending pulls to Torvalds directly
for IIO to cut the intermediary staging tree step, since
now the subsystem is pretty large and see a bunch of
frequent fixes that need an express path to Torvalds.

Pushing through Greg per se isn't really the problem,
I think the problem is that IIO is going through the
staging tree which (I guess) isn't a high priority activity
and not expected to carry any serious critical fixes and
I guess this can cause lags.

Maybe Greg has some other branch to take in IIO
fixes and for-next but I don't really see the point.

The IIO left in the staging tree is just regular staging
business at this point, the main IIO is much more
important.

Linus 2: would pulling the IIO tree directly work for
you if Jonathan makes up his mind in favor for that?

Yours,
Linus Walleij
