        drivers/net/wireless/ath/wil6210/wmi.c:746 wmi_recv_cmd()
        info: ignoring unreachable code.

drivers/net/wireless/ath/wil6210/wmi.c
   739                  spin_unlock_irqrestore(&wil->wmi_ev_lock, flags);
   740                  {
   741                          int q = queue_work(wil->wmi_wq,
   742                                             &wil->wmi_event_worker);
   743                          wil_dbg_wmi(wil, "queue_work -> %d\n", q);
   744                  }
   745          }
   746          if (n > 1)
                ^^^^^^^^^^
We never reach this if statemtent.

   747                  wil_dbg_wmi(wil, "%s -> %d events processed\n", __func__, n);
   748  }

Exit loop with "break", not "return".
