cfg80211/mac80211: enable proper device_set_wakeup_enable handling
In WoWLAN, we only get the triggers when we actually get to suspend. As a consequence, drivers currently don't know that the device should enable wakeup. However, the device_set_wakeup_enable() API is intended to be called when the wakeup is enabled, not later when needed. Add a new set_wakeup() call to cfg80211 and mac80211 to allow drivers to properly call device_set_wakeup_enable. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
