Power management and ACPI fixes for v4.2-rc1

Browse source 
- Fix a recently added memory leak in an error path in the ACPI
    resources management code (Dan Carpenter).
 
  - Fix a build warning triggered by an ACPI video header function
    that should be static inline (Borislav Petkov).
 
  - Change names of helper function converting struct fwnode_handle
    pointers to either struct device_node or struct acpi_device
    pointers so they don't conflict with local variable names
    (Alexander Sverdlin).
 
  - Make the hibernate core re-enable nonboot CPUs on failures to
    disable them as expected (Vitaly Kuznetsov).
 
  - Increase the default timeout of the device suspend watchdog to
    prevent it from triggering too early on some systems (Takashi Iwai).
 
  - Prevent the cpuidle powernv driver from registering idle
    states with CPUIDLE_FLAG_TIMER_STOP set if CONFIG_TICK_ONESHOT
    is unset which leads to boot hangs (Preeti U Murthy).

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are fixes that didn't make it to the previous PM+ACPI pull
  request or are fixing issues introduced by it.

  Specifics:

   - Fix a recently added memory leak in an error path in the ACPI
     resources management code (Dan Carpenter)

   - Fix a build warning triggered by an ACPI video header function that
     should be static inline (Borislav Petkov)

   - Change names of helper function converting struct fwnode_handle
     pointers to either struct device_node or struct acpi_device
     pointers so they don't conflict with local variable names

* tag 'pm+acpi-4.2-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  tick/idle/powerpc: Do not register idle states with CPUIDLE_FLAG_TIMER_STOP set in periodic mode
  PM / sleep: Increase default DPM watchdog timeout to 60
  PM / hibernate: re-enable nonboot cpus on disable_nonboot_cpus() failure
  ACPI / OF: Rename of_node() and acpi_node() to to_of_node() and to_acpi_node()
  ACPI / video: Inline acpi_video_set_dmi_backlight_type
  ACPI / resources: free memory on error in add_region_before()
