From: Johan Hovold <johan@xxxxxxxxxx>
commit 2d9a00705910ccea2dc5d9cba5469ff2de72fc87 upstream.
In the unlikely event that setting the software flow-control characters
fails the other flow-control settings should still be updated (just like
all other terminal settings).
Move out the error message printed by the set_chars() helper to make it
more obvious that this is intentional.
Fixes: 7748feffcd80 ("USB: serial: cp210x: add support for software flow control")
