Power management and ACPI fixes for v4.4-rc7

Browse Source 
- Fix a thermal management issue introduced by an ACPI processor
    driver change made during the 4.3 development cycle that failed
    to return 0 from a function on success which triggered an error
    cleanup path every time it had been called that deleted useful
    data structures created previously (Srinivas Pandruvada).
 
  - Fix a variable data type issue in the arm_big_little cpufreq
    driver's SCPI support code added recently that prevents error
    handling in there from working correctly (Dan Carpenter).

Pull power management and ACPI fixes from Rafael Wysocki:
 "These fix an ACPI processor driver regression introduced during the
  4.3 cycle and a mistake in the recently added SCPI support in the
  arm_big_little cpufreq driver.

  Specifics:

   - Fix a thermal management issue introduced by an ACPI processor
     driver change made during the 4.3 development cycle that failed to
     return 0 from a function on success which triggered an error
     cleanup path every time it had been called that deleted useful data
     structures created previously (Srinivas Pandruvada).

   - Fix a variable data type issue in the arm_big_little cpufreq
     driver's SCPI support code added recently that prevents error
     handling in there from working correctly (Dan Carpenter)"
