PM / sleep: Mechanism for aborting system suspends unconditionally
It sometimes may be necessary to abort a system suspend in progress or wake up the system from suspend-to-idle even if the pm_wakeup_event()/pm_stay_awake() mechanism is not enabled. For this purpose, introduce a new global variable pm_abort_suspend and make pm_wakeup_pending() check its value. Also add routines for manipulating that variable. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
