      rtlwifi: Fix kernel Oops "Fw download fail!!" · 12dfa2f6
      Ping-Ke Shih authored
      When connecting to AP, mac80211 asks driver to enter and leave PS quickly,
      but driver deinit doesn't wait for delayed work complete when entering PS,
      then driver reinit procedure and delay work are running simultaneously.
      This will cause unpredictable kernel oops or crash like

      This patch ensures all delayed works done before entering PS to satisfy
      our expectation, so use cancel_delayed_work_sync() instead. An exception
      is delayed work ips_nic_off_wq because running task may be itself, so add
      a parameter ips_wq to deinit function to handle this case.
