[PATCH] PCI PM: Make pci_prepare_to_sleep() disable wake-up if needed

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@xxxxxxx>

If the device is not supposed to wake up the system, ie. when
device_may_wakeup(&dev->dev) returns 'false', pci_prepare_to_sleep()
should pass 'false' to pci_enable_wake() so that it calls the
platform to disable the wake-up capability of the device.
