driver-core

Pull driver core fixes from Greg KH:
 "Here are two driver core fixes for 4.9-rc5.

  The first resolves an issue with some drivers not liking to be unbound
  and bound again (if CONFIG_DEBUG_TEST_DRIVER_REMOVE is enabled), which
  solves some reported problems with graphics and storage drivers. The
  other resolves a smatch error with the 4.9-rc1 driver core changes
  around this feature.

  Both have been in linux-next with no reported issues"

* tag 'driver-core-4.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
  driver core: fix smatch warning on dev->bus check
  driver core: skip removal test for non-removable drivers
