sky2: Fix WOL regression
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 <rjw@sisk.pl> Cc: Tino Keitel <tino.keitel@gmx.de> Signed-off-by: David S.
