Merge tag 'staging-4.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging and IIO driver fixes from Greg KH:
"Here are some IIO and staging driver fixes for 4.5-rc3.

All of them, except one, are for IIO drivers, and one is for a speakup
driver fix caused by some earlier patches, to resolve a reported build
failure"
