    wireless : use a dedicated workqueue for cfg80211. · e60d7443
    Alban Browaeys authored
    This patch moves the works cleanup, scan and events to a cfg80211
    dedicated workqueue.
    Platform driver like eeepc-laptop ought to use works to rfkill (as
    new rfkill does lock in rfkill_unregister and the platform driver is
    called from rfkill_switch_all which also lock the same mutex).
    This raise a new issue in itself that the work scheduled by the platform
    driver to the global worqueue calls wiphy_unregister which flush_work
    scan and event works (which thus flush works on the global workqueue inside
    a work on the global workqueue) and also put on hold the  wdev_cleanup_work
     (which prevents the dev_put on netdev thus indefinite Usage count error on
    wifi device).
