Linville 1292270108 -0500 mac80211: avoid calling ieee80211_work_work unconditionally On suspend, there might be usb wireless drivers which wrongly trigger the warning in ieee80211_work_work. If an usb driver doesn't have a suspend hook, the usb stack will disconnect the device. On disconnect, a mac80211 driver calls ieee80211_unregister_hw, which calls dev_close, which calls ieee80211_stop, and in the end calls ieee80211_work_purge-> ieee80211_work_work. The problem is that this call to ieee80211_work_purge comes after mac80211 is suspended, triggering the warning even when we don't have work queued in work_list (the expected case when already suspended), because it always calls ieee80211_work_work. So, just call ieee80211_work_work in ieee80211_work_purge if we really have to abort work.
