tty/serial: atmel: fix TX path in atmel_console_write() commit 497e1e16f45c70574dc9922c7f75c642c2162119 upstream. A side effect of 89d8232411a8 ("tty/serial: atmel_serial: BUG: stop DMA from transmitting in stop_tx") is that the console can be called with TX path disabled. Then the system would hang trying to push charecters out in atmel_console_putchar().
