Linus Torvalds 30f05309bd More power management and ACPI updates for v4.5-rc1
- Modify the driver core and the USB subsystem to allow USB devices
    to stay suspended over system suspend/resume cycles if they have
    been runtime-suspended already beforehand and fix some bugs on
    top of these changes (Tomeu Vizoso, Rafael Wysocki).
 
  - Update ACPICA to upstream revision 20160108, including updates
    of the ACPICA's copyright notices, a code fixup resulting from
    a regression fix that was necessary in the upstream code only
    (the regression fixed by it has never been present in Linux)
    and a compiler warning fix (Bob Moore, Lv Zheng).
 
  - Fix a recent regression in the cpuidle menu governor that broke
    it on practically all architectures other than x86 and make a
    couple of optimizations on top of that fix (Rafael Wysocki).
 
  - Clean up the selection of cpuidle governors depending on whether
    or not the kernel is configured for tickless systems (Jean Delvare).
 
  - Revert a recent commit that introduced a regression in the ACPI
    backlight driver, address the problem it attempted to fix in a
    different way and revert one more cosmetic change depending on
    the problematic commit (Hans de Goede).
 
  - Add two more ACPI backlight quirks (Hans de Goede).
 
  - Fix a few minor problems in the core devfreq code, clean it up
    a bit and update the MAINTAINERS information related to it
    (Chanwoo Choi, MyungJoo Ham).
 
  - Improve an error message in the ACPI fan driver (Andy Lutomirski).
 
  - Fix a recent build regression in the cpupower tool (Shreyas Prabhu).

Merge tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management and ACPI updates from Rafael Wysocki:
 "This includes fixes on top of the previous batch of PM+ACPI updates
  and some new material as well.

  From the new material perspective the most significant are the driver
  core changes that should allow USB devices to stay suspended over
  system suspend/resume cycles if they have been runtime-suspended
  already beforehand.  Apart from that, ACPICA is updated to upstream
  revision 20160108 (cosmetic mostly, but including one fixup on top of
  the previous ACPICA update) and there are some devfreq updates the
  didn't make it before (due to timing).

  A few recent regressions are fixed, most importantly in the cpuidle
  menu governor and in the ACPI backlight driver and some x86 platform
  drivers depending on it.

  Some more bugs are fixed and cleanups are made on top of that.

  Specifics:

   - Modify the driver core and the USB subsystem to allow USB devices
     to stay suspended over system suspend/resume cycles if they have
     been runtime-suspended already beforehand and fix some bugs on top
     of these changes (Tomeu Vizoso, Rafael Wysocki).

     the ACPICA's copyright notices, a code fixup resulting from a

     regression fixed by it has never been present in Linux) and a
     compiler warning fix (Bob Moore, Lv Zheng).

     on practically all architectures other than x86 and make a couple
     of optimizations on top of that fix (Rafael Wysocki).
