[PATCH 3/3] tty: serial: altera: use altera_jtaguart_stop_tx()

From: Jiri Slaby
Date: Mon Apr 11 2022 - 06:45:31 EST


altera_jtaguart_tx_chars() duplicates what altera_jtaguart_stop_tx()
already does. So instead of the duplication, call the helper instead.

Not only it makes the code cleaner, but it also says what the "if"
really does.
