patch "USB: serial: ch341: fix initial modem-control state" added to usb-linus

[gregkh]

This is a note to let you know that I've just added the patch titled

    USB: serial: ch341: fix initial modem-control state

to my usb git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: USB: serial: ch341: fix initial modem-control state

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.
