Merge tag 'driver-core-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull driver core patches from Greg KH:
 "Here's the big driver core pull request for 3.12-rc1.

  Lots of tiny changes here fixing up the way sysfs attributes are
  created, to try to make drivers simpler, and fix a whole class race
  conditions with creations of device attributes after the device was
  announced to userspace.

  All the various pieces are acked by the different subsystem
  maintainers"
