Power management fixes for v4.10-rc1

Browse Source 
- Prevent the acpi-cpufreq driver from crashing on exit by fixing
    a check against the __cpuhp_setup_state() return value and fix
    the kerneldoc description of that function to make it clear that
    it may return positive numbers on success too (Boris Ostrovsky).
 
  - Drop an incorrect __init annotation of a function in the
    s3c64xx cpufreq driver and fix a build warning generated (by
    older compilers) because of it (Arnd Bergmann).

Pull power management fixes from Rafael Wysocki:
 "They fix one bug introduced recently, a build warning and a kerneldoc
  function description.

  Specifics:

   - Prevent the acpi-cpufreq driver from crashing on exit by fixing a
     check against the __cpuhp_setup_state() return value and fix the
     kerneldoc description of that function to make it clear that it may
     return positive numbers on success too (Boris Ostrovsky)

   - Drop an incorrect __init annotation of a function in the s3c64xx
     cpufreq driver and fix a build warning generated (by older
     compilers) because of it (Arnd Bergmann)"

* tag 'pm-fixes-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  cpufreq: s3c64xx: remove incorrect __init annotation
  cpufreq: Remove CPU hotplug callbacks only if they were initialized
  CPU/hotplug: Clarify description of __cpuhp_setup_state() return value
