2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Rafael J. Wysocki commit 6ff68026f4757d68461b7fbeca5c944e1f5f8b44 upstream. Since dev->power.should_wakeup bit is used by the PCI core to decide whether the device should wake up the system from sleep states, set/unset this bit whenever WOL is enabled/disabled using e1000_set_wol(). Accordingly, use device_can_wakeup() for checking if wake-up is supported by the device. Signed-off-by: Rafael J. Wysocki Signed-off-by: Jeff Kirsher Signed-off-by: David S.
