Re: [PULL] Second round of IIO new device support, functionality, cleanups and docs for the 4.3 cycle.

[Jonathan Cameron <jic23@kernel.org>]

Hi Greg,

There will be a merge conflict in here with mlx90614.c.
Another easy one.  Keep the defines version as it
has the correct values (was previously a wrong sign in
there).  Quite a lot of automerges as well in this one
but they seem to have gone fine.

Hartmut has been very busy so I have quite a few patches
queued up that are dependent on fixes working there way
through to this tree as I obviously haven't sent you a pull
request for quite a while.

Thanks

Jonathan
