      the code is fine but needs lockdep annotation.

      mac80211: cancel restart_work explicitly instead of depending on flush_scheduled_work() · 99b88a0e
      Tejun Heo authored
      iee80211_hw->restart_work is the only work which uses the system
      workqueue.  Instead of calling flush_scheduled_work() during
      iee80211_exit(), cancel the work during unregistration.
      
      This is to prepare for the deprecation and removal of
      flush_scheduled_work().
