Merge tag 'driver-core-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core fixes from Greg KH:
 "Here are a few small fixes for 4.14-rc4.

  The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one
  straggler made it in through some other tree (odds are, one of
  mine...) So there's a simple removal of the last user, and then
  finally the macro is removed from the tree.

  There's a fix for old crazy udev instances that insist on reloading a
  module when it is removed from the kernel due to the new uevents for
  bind/unbind. This fixes the reported regression, hopefully some year
  in the future we can drop the workaround, once users update to the
  latest version, but I'm not holding my breath.

  And then there's a build fix for a linker warning, and a buffer
  overflow fix to match the PCI fixes you took through the PCI tree in
  the same area.

  All of these have been in linux-next for a few weeks while I've been
  traveling, sorry for the delay"
