The USB_DEVICE_INTERFACE_NUMBER matching macro assumes that the { vendorid, productid, interfacenumber } set uniquely identifies one specific function. This has proven to fail for some configurable devices. One example is the Quectel EM06/EP06 where the same interface number can be either QMI or MBIM, without the device ID changing either. Fix by requiring the vendor-specific class for interface number based matching. Functions of other classes can and should use class based matching instead.
