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 kernel/power/process.c | 5 ++++- kernel/power/suspend.c | 15 ++++++++++++++- 2 files changed, 18 insertions(+), 2 deletions(-)
