This copy is checked when deciding whether or not to return to sleep in IEEE PS mode but the actual copying back to priv was omitted, which breaks IEEE PS mode with WPA/WPA2 when one issues commands that require temporarily keeping the device awake. This patch introduces the omitted copy-back of the keys so that IEEE PS functions correctly in WPA/WPA2 mode. Thanks to Dan Williams for clearing up the issue.
