Subject: [PATCH] PCI PM: Make pci_prepare_to_sleep() disable wake-up if needed
Date: Sat, 28 Mar 2009 22:26:15 +0100 [thread overview]
Message-ID: <200903282226.15511.rjw@sisk.pl> (raw)
From: Rafael J. Wysocki <rjw@sisk.pl>
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.
