Merge tag 'staging-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO updates from Greg KH:
"Here's the "big" staging/iio pull request for 4.10-rc1.
Not as big as 4.9 was, but still just over a thousand changes. We
almost broke even of lines added vs. removed, as the slicoss driver
was removed (got a "clean" driver for the same hardware through the
netdev tree), and some iio drivers were also dropped, but I think we
ended up adding a few thousand lines to the source tree in the end.
Other than that it's a lot of minor fixes all over the place, nothing
major stands out at all.
All of these have been in linux-next for a while. There will be a
merge conflict with Al's vfs tree in the lustre code, but the
resolution for that should be pretty simple, that too has been in
linux-next"
