Merge tag 'driver-core-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core patches from Greg KH:
 "Really tiny set of patches for this kernel.  Nothing major, all
  described in the shortlog and have been in linux-next for a while"

* tag 'driver-core-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
  sysfs: fix warning when creating a sysfs group without attributes
  firmware_loader: handle timeout via wait_for_completion_interruptible_timeout()
  firmware_loader: abort request if wait_for_completion is interrupted
  firmware: Correct function name in comment
  device: Change dev_<level> logging functions to return void
  device: Fix dev_dbg_once macro
