    bwi: Mark write-only variable as __unused
    
    We read TX_STATUS1 to acknowledge a TX interrupt. We don't use this
    value for anything, so mark it as unused. We may be able to eliminate
    this read, but since this hardware is poorly documented and difficult to
    test, I'm leaving the read in place.
