Merge tag 'pm+acpi-4.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull power management and ACPI fixes from Rafael Wysocki:
 "Just two fixes, one for an ACPI LPSS driver issue introduced during
  the 3.17 cycle and one revert of a recent commit that sort of broke
  the cpupower tool.

  Specifics:

   - Fix an ACPI LPSS (Low-Power Subsystem) driver issue causing the
     8250_dw driver to confuse an LPSS clock with another one it is
     supposed to handle due to the lack of identification allowing it to
     tell those clocks apart (Heikki Krogerus).

   - Revert a recent commit that was supposed to improve the usability
     of the cpupower tool, but clearly did the opposite (Josh Boyer)"

* tag 'pm+acpi-4.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  Revert "cpupower Makefile change to help run the tool without 'make install'"
