Subject: [PATCH v2 -next 0/2] PM: suspend: Optimized suspend is fail returned by wakeup

Changes in v2:
* fix a build test ERROR reported by kernel test robot.
* Increase the initial value of the pm_suspend_target_state variable to
  prevent the situation where it was not assigned before the call from
  freeze_process().

Cover letter from v1:

When the suspend process is executed from the /sys/power/state entry,
the pm_wakeup_clear() signal is cleared in advance, and the wakeup
signal can be captured to fail the suspend process when the suspend
process is notified by the notifier;

Expanding the scope of the pm_suspend_target_state variable also allows
the device driver to know that the system has entered the suspend
process earlier.

xiongxin (2):
  PM: suspend: expand the assignment scope of the
    pm_suspend_target_state
  PM: suspend: advanced pm_wakeup_clear() for normal suspend/hibernate
