      wifi: mt76: mt7921e: fix crash in chip reset fail · fa3fbe64
      Deren Wu authored
      In case of drv own fail in reset, we may need to run mac_reset several
      times. The sequence would trigger system crash as the log below.
      
      Because we do not re-enable/schedule "tx_napi" before disable it again,
      the process would keep waiting for state change in napi_diable(). To
      avoid the problem and keep status synchronize for each run, goto final
      resource handling if drv own failed.
