4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Johan Hovold <johan@xxxxxxxxxx> 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.
