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().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
