commit 030ee7ae upstream. The modem-control signals are managed by the tty-layer during open and should not be asserted prematurely when set_termios is called from driver open. Also make sure that the signals are asserted only when changing speed from B0. Fixes: 664d5df9 ("USB: usb-serial ch341: support for DTR/RTS/CTS") Signed-off-by:
