2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Rafael J. Wysocki commit 9d731d77c9794bb0a264f58d35949a1ab6dcc41c 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 sky2_set_wol(). Remove an open-coded reference to the standard PCI PM registers that is not used any more. Signed-off-by: Rafael J. Wysocki Cc: Tino Keitel Signed-off-by: David S.
