Merge tag 'driver-core-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core merge from Greg Kroah-Hartman:
 "Here is the big driver core update for 3.7-rc1.

  A number of firmware_class.c updates (as you saw a month or so ago),
  and some hyper-v updates and some printk fixes as well.  All patches
  that are outside of the drivers/base area have been acked by the
  respective maintainers, and have all been in the linux-next tree for a
  while.

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"
