From: Johan Hovold <jo...@kernel.org>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 4e2da44691cffbfffb1535f478d19bc2dca3e62b upstream.
DTR and RTS will be asserted by the tty-layer when the port is opened
and deasserted on close (if HUPCL is set). Make sure the initial state
is not-asserted before the port is first opened as well.
Fixes: 664d5df92e88 ("USB: usb-serial ch341: support for DTR/RTS/CTS")
