    cfg80211: fix dangling scan request checking · ad002395
    Johannes Berg authored
    My patch "cfg80211: fix deadlock" broke the code it
    was supposed to fix, the scan request checking. But
    it's not trivial to put it back the way it was, since
    the original patch had a deadlock.
    Now do it in a completely new way: queue the check
    off to a work struct, where we can freely lock. But
    that has some more complications, like needing to
    wait for it to be done before the wiphy/rdev can be
    destroyed, so some code is required to handle that.
