This patch add the iio_device_get() function, which increases the reference

iio_device_put() - already exists.

Hi Jonathan,
Are you OK with these two patches?
Sorry, was a somewhat mad week..
Acked-by: Jonathan Cameron<jic23@xxxxxxxxxx>
for both of them.
Thanks. Btw. these touch only out-of-staging IIO code. Now that the
out-of-staging code is in mainline, what's the plan for the patch flow? Are
you going to collect the patches and send them to Linus or should they still
go through the staging tree?
Greg has kindly agreed to continue handling patches during this period
(I'll start building up to take over in the longer run).
I'm not actually sure how he will want to split stuff as obviously a lot
of patches, not including this one, will touch both the stuff in staging
and the stuff that isn't...
For now send patches to Greg and see what he does with them I guess!
Make it clear in the cover letter what they effect though.
Jonathan
