[PATCH] usb_serial: Stop passing NULL to functions that expect data

From: Alan Cox
Date: Wed Sep 26 2007 - 18:02:49 EST

Earlier patches have removed the checking for old v new differences from
the USB drivers so we can now pass in a valid blank old termios so that
we don't to fill the drivers with magic hacks for console support
