Pull driver core updates from Greg KH:
"Very tiny pull request for 4.12-rc1 for the driver core this time
around.
There are some documentation fixes, an eventpoll.h fixup to make it
easier for the libc developers to take our header files directly, and
some very minor driver core fixes and changes.
All have been in linux-next for a very long time with no reported
issues"
