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
