PM / wakeirq: report a wakeup_event on dedicated wekup irq
There are two reasons for reporting wakeup event when dedicated wakeup IRQ is triggered: - wakeup events accounting, so proper statistical data will be displayed in sysfs and debugfs; - there are small window when System is entering suspend during which dedicated wakeup IRQ can be lost: dpm_suspend_noirq() |- device_wakeup_arm_wake_irqs() |- dev_pm_arm_wake_irq(X) |- IRQ is enabled and marked as wakeup source [1]... |- suspend_device_irqs() |- suspend_device_irq(X) |- irqd_set(X, IRQD_WAKEUP_ARMED); |- wakup IRQ armed The wakeup IRQ can be lost if it's triggered at point [1] and not armed yet. Hence, fix above cases by adding simple pm_wakeup_event() call in handle_threaded_wake_irq().
