I can't apply patches 1-2 and 5-6 since they depend on patches 3-4 for
which I'd need an Acked-by: from Lee if I'm to pick them up. Same goes
for patch 7.

By the looks of it there are minor conflicts with the MFD tree, but no
major ones. Perhaps it'd be better for Lee to pick up 3-4 for v4.17-rc1
and ack patch 7, then I can take the rest after v4.17-rc1?
