Power management and ACPI material for v4.2-rc2

Browse source 
- Fix for an ACPI resources management regression introduced
    during the 4.1 cycle (that unfortunately went into -stable)
    effectively reverting the bad commit along with the recent
    fixups on top of it and using an alternative approach to
    address the underlying issue (Rafael J Wysocki).
 
  - Fix for a memory leak and an incorrect return value in an
    error code path in the ACPI LPSS (Low-Power Subsystem) driver
    (Rafael J Wysocki).
 
  - Fix for a leftover dangling pointer in an error code path in
    the new wakeup IRQ support code (Rafael J Wysocki).
 
  - Fix to prevent infinite loops (due to errors in other places)
    from happening in the core generic PM domains support code
    (Geert Uytterhoeven).
 
  - Hibernation documentation update/clarification (Uwe Geuder).
 
  - Support for _CLS-based device enumeration in the ACPI core
    and in the ATA subsystem (Suravee Suthikulpanit).

Merge tag 'pm+acpi-4.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI updates from Rafael Wysocki:
 "These are fixes on top of the previous PM+ACPI pull requests
  (including one fix for a 4.1 regression) and two commits adding
  _CLS-based device enumeration support to the ACPI core and the ATA
  subsystem that waited for the latest ACPICA changes to be merged.

  Specifics:

   - Fix for an ACPI resources management regression introduced during
     the 4.1 cycle (that unfortunately went into -stable) effectively
     reverting the bad commit along with the recent fixups on top of it
     and using an alternative approach to address the underlying issue
     (Rafael J Wysocki).

   - Fix for a memory leak and an incorrect return value in an error
     code path in the ACPI LPSS (Low-Power Subsystem) driver (Rafael J
     Wysocki).

   - Fix for a leftover dangling pointer in an error code path in the
     new wakeup IRQ support code (Rafael J Wysocki).

   - Fix to prevent infinite loops (due to errors in other places) from
     happening in the core generic PM domains support code (Geert
     Uytterhoeven).

   - Hibernation documentation update/clarification (Uwe Geuder).

   - Support for _CLS-based device enumeration in the ACPI core and in
     the ATA subsystem (Suravee Suthikulpanit)"
