Linus Torvalds b7356abb9f Power management and ACPI fixes for 3.11-rc2
- Two cpufreq commits from the 3.10 cycle introduced regressions.
   The first of them was buggy (it did way much more than it needed
   to do) and the second one attempted to fix an issue introduced by
   the first one.  Fixes from Srivatsa S Bhat revert both.
 
 - If autosleep triggers during system shutdown and the shutdown
   callbacks of some device drivers have been called already, it may
   crash the system.  Fix from Liu Shuo prevents that from happening
   by making try_to_suspend() check system_state.
 
 - The ACPI memory hotplug driver doesn't clear its driver_data on
   errors which may cause a NULL poiter dereference to happen later.
   Fix from Toshi Kani.
 
 - The ACPI namespace scanning code should not try to attach scan
   handlers to device objects that have them already, which may confuse
   things quite a bit, and it should rescan the whole namespace branch
   starting at the given node after receiving a bus check notify event
   even if the device at that particular node has been discovered
   already.  Fixes from Rafael J Wysocki.
 
 - New ACPI video blacklist entry for a system whose initial backlight
   setting from the BIOS doesn't make sense.  From Lan Tianyu.
 
 - Garbage string output avoindance for ACPI PNP from Liu Shuo.
 
 - Two Kconfig fixes for issues introduced recently in the s3c24xx
   cpufreq driver (when moving the driver to drivers/cpufreq) from
   Paul Bolle.
 
 - Trivial comment fix in pm_wakeup.h from Chanwoo Choi.

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are fixes collected over the last week, most importnatly two
  cpufreq reverts fixing regressions introduced in 3.10, an autoseelp
  fix preventing systems using it from crashing during shutdown and two
  ACPI scan fixes related to hotplug.

  Specifics:

   - Two cpufreq commits from the 3.10 cycle introduced regressions.
     The first of them was buggy (it did way much more than it needed to
     do) and the second one attempted to fix an issue introduced by the
     first one.  Fixes from Srivatsa S Bhat revert both.

   - If autosleep triggers during system shutdown and the shutdown
     callbacks of some device drivers have been called already, it may
     crash the system.  Fix from Liu Shuo prevents that from happening
     by making try_to_suspend() check system_state.

   - The ACPI memory hotplug driver doesn't clear its driver_data on
     errors which may cause a NULL poiter dereference to happen later.
     Fix from Toshi Kani.

   - The ACPI namespace scanning code should not try to attach scan
     handlers to device objects that have them already, which may
     confuse things quite a bit, and it should rescan the whole
     namespace branch starting at the given node after receiving a bus
     check notify event even if the device at that particular node has
     been discovered already.  Fixes from Rafael J Wysocki.

   - New ACPI video blacklist entry for a system whose initial backlight
     setting from the BIOS doesn't make sense.  From Lan Tianyu.

   - Garbage string output avoindance for ACPI PNP from Liu Shuo.

   - Two Kconfig fixes for issues introduced recently in the s3c24xx
     cpufreq driver (when moving the driver to drivers/cpufreq) from
     Paul Bolle.

   - Trivial comment fix in pm_wakeup.h from Chanwoo Choi"
