Merge tag 'driver-core-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core into next
Pull driver core / kernfs changes from Greg KH:
"Here is the "big" pull request for 3.16-rc1.
Not a lot of changes here, some kernfs work, a revert of a very old
driver core change that ended up cauing some memory leaks on driver
probe error paths, and other minor things.
As was pointed out earlier today, one commit here, 26fc9cd200ec
("kernfs: move the last knowledge of sysfs out from kernfs") is also
needed in your 3.15-final branch as well. If you could cherry-pick it
there, it would be most appreciated by Andy Lutomirski to prevent a
regression there.
All of these have been in linux-next for a while"
