Merge tag 'driver-core-4.1-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core fixes from Greg KH:
 "Here are two fixes for the driver core that resolve some reported
  issues.

  One is a regression from 4.0, the other a fixes a reported oops that
  has been there since 3.19.

  Both have been in linux-next for a while with no problems"
