Subject: sky2: fix recent WOL regression
From: Rafael J. Wysocki <rjw@xxxxxxx>
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() (this fixes
a regression from 2.6.26 on the Tino's machine).
Remove an open-coded reference to the standard PCI PM registers that is
not used any more.
