[046/136] tty: remove dtr/rts use from the driver open methods

[Greg KH]

2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Alan Cox <alan@xxxxxxxxxxxxxxx>

commit 9a68e39d4a701fb3be03cae9b462408664ebd205 upstream.

These are handled by the tty_port core code which will raise and lower the
carrier correctly in tty_wait_until_ready
