The wakeup.prepared flag is used for marking devices that have the wake-up power already enabled, so that the wake-up power is not enabled twice in a row for the same device. This assumes, however, that device wake-up power will only be enabled once, while the device is being prepared for a system-wide sleep transition, and the second attempt is made by acpi_enable_wakeup_device_prep(). With the upcoming PCI wake-up rework this assumption will not hold any more for PCI bridges and the root bridge whose wake-up power may be enabled as a result of wake-up enable propagation from other devices (eg. add-on devices that are not associated with any GPEs). Thus, there may be many attempts to enable wake-up power on a PCI bridge or the root bridge during a system power state transition and it's better to replace wakeup.prepared with a reference counter.
