Merge tag 'pm+acpi-4.2-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

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
     (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)"

* 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()
