    [SERIAL] Fix another SMP deadlock with modem status signal changes · 1cc1381e

    The original fix sent to Ingo for stop_tx didn't take account that
    the start_tx and stop_tx methods can be called from the device
    specific code under the port spinlock.  Consequently, we move the
    spinlock to the callers of these methods.  Documentation updated
    to reflect the change.
