Re: [PULL] Second set of IIO new core stuff and drivers for the 4.5 cycle

[Jonathan Cameron <jic23@kernel.org>]

Hi Greg,

I'm going to send you a pull request that builds on top of this one as
our final IIO one for this cycle. It's pretty small but involves at
least one fix for a patch in this cycle.

If you particularly want me to combine them into a single pull request
then give me a shout.

Jonathan
