Gregory Nutt 9a8c3572db serial.c: Fix a race condition noted by Stefan Kolb. Between the test if the TX buffer is full and entering a critical section, bytes may be removed from the TX buffer making the wait unnecessary. The unnecessary wait is an inefficiency, but not really a problem. But with USB CDC/ACM it can be a problem because the entire TX buffer may be emptied when we lose the race. If that happens that uart_putxmitchar() can hang waiting for data to be removed from an empty TX buffer.		2016-07-22 07:47:59 -06:00
