Subject[51/67] USB: option: add huawei k3765 k4505 devices to work properly
2.6.35-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Andrew Bird <ajb@spheresystems.co.uk>

commit 0372a754be9aa43e19fd86c9bc04796d43b55e38 upstream.

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.
