Merge tag 'driver-core-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core patches for 3.4-rc1 from Greg KH:
"Here's the big driver core merge for 3.4-rc1.
Lots of various things here, sysfs fixes/tweaks (with the nlink
breakage reverted), dynamic debugging updates, w1 drivers, hyperv
driver updates, and a variety of other bits and pieces, full
information in the shortlog."
