This patch adds the product IDs of Huawei's K3765 and K4505 mobile broadband
usb modems to option.c. It also adds a quirk to the option probe function so
that binding to the device's network interface(class 0xff) is avoided. This is
necessary to allow another driver to bind to that, and to avoid programs like
wvdial opening a nonfunctioning tty during modem discovery.
