    Pull more ACPI and power management updates from Rafael Wysocki:
     "These are regression fixes (leds-gpio, ACPI backlight driver,
      operating performance points library, ACPI device enumeration
      messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device
      PM), some cleanups in the operating performance points (OPP)
      framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of
      minor intel_pstate driver changes, a new MAINTAINERS entry for it and
      an ACPI fan driver change needed for better support of thermal
      management in user space.
    
      Specifics:
    
       - Fix a regression in leds-gpio introduced by a recent commit that
         inadvertently changed the name of one of the properties used by the
         driver (Fabio Estevam).
    
       - Fix a regression in the ACPI backlight driver introduced by a
         recent fix that missed one special case that had to be taken into
         account (Aaron Lu).
    
       - Drop the level of some new kernel messages from the ACPI core
         introduced by a recent commit to KERN_DEBUG which they should have
         used from the start and drop some other unuseful KERN_ERR messages
         printed by ACPI (Rafael J Wysocki).
    
       - Revert an incorrect commit modifying the cpupower tool (Prarit
         Bhargava).
    
       - Fix two regressions introduced by recent commits in the OPP library
         and clean up some existing minor issues in that code (Viresh
         Kumar).
    
       - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the
         tree (or drop it where that can be done) in order to make it
         possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf
         Hansson, Ludovic Desroches).
    
         There will be one more "CONFIG_PM_RUNTIME removal" batch after this
         one, because some new uses of it have been introduced during the
         current merge window, but that should be sufficient to finally get
         rid of it.
    
       - Make the ACPI EC driver more robust against race conditions related
         to GPE handler installation failures (Lv Zheng).
    
       - Prevent the ACPI device PM core code from attempting to disable
         GPEs that it has not enabled which confuses ACPICA and makes it
         report errors unnecessarily (Rafael J Wysocki).
    
       - Add a "force" command line switch to the intel_pstate driver to
         make it possible to override the blacklisting of some systems in
         that driver if needed (Ethan Zhao).
    
       - Improve intel_pstate code documentation and add a MAINTAINERS entry
         for it (Kristen Carlson Accardi).
    
       - Make the ACPI fan driver create cooling device interfaces witn
         names that reflect the IDs of the ACPI device objects they are
         associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").
    
         That's necessary for user space thermal management tools to be able
         to connect the fans with the parts of the system they are supposed
         to be cooling properly.  From Srinivas Pandruvada"
