The home cooked whitelisting code can be removed now that 
the USB core supports interface number matching.

The second patch adds a few new devices.

The third patch improves device list readability by using
existing macros where possible.

I hope this can go in 3.6-rc2/3. The series is based on
the current net/master (commit 2359a476)

This driver support many composite USB devices where the
interface class/subclass/protocol provides no information
about the interface function. Interfaces with different
functions may all use ff/ff/ff, like this example of
a device with three serial interfaces and three QMI/wwan
interfaces:

Instead of class/subclass/protocol the vendor use fixed
interface numbers for each function, and the Windows
drivers use these numbers to match driver and function.

The driver has had its own interface number whitelisting
code to simulate this functionality.  Replace this with
generic interface number matching now that the USB subsystem
support is there. This
 - removes the need for a driver_info structure per
   interface number,
 - avoids running the probe function for unsupported
   interfaces, and
 - simplifies the code.

Add 6 new devices and one modified device, based on
information from laptop vendor Windows drivers.

Sony provides a driver with two new devices using
a Gobi 2k+ layout (1199:68a5 and 1199:68a9).  The
Sony driver also adds a non-standard QMI/net
interface to the already supported 1199:9011
Gobi device. We do not know whether this is an
alternate interface number or an additional
interface which might be present, but that doesn't
really matter.

Lenovo provides a driver supporting 4 new devices:
 - MC7770 (1199:901b) with standard Gobi 2k+ layout
 - MC7700 (0f3d:68a2) with layout similar to MC7710
 - MC7750 (114f:68a2) with layout similar to MC7710
 - EM7700 (1199:901c) with layout similar to MC7710

Note regaring the three devices similar to MC7710:

The Windows drivers only support interface #8 on these
devices.  The MC7710 can support QMI/net functions on
interface #19 and #20 as well, and this driver is
verified to work on interface #19 (a firmware bug is
suspected to prevent #20 from working).

We do not enable these additional interfaces until they
either show up in a Windows driver or are verified to
work in some other way.  Therefore limiting the new
devices to interface #8 for now.

Take advantage of the matching macros to make the device id
list easier to read and maintain.

Just an additional afterthought: Please do not apply this as it is to
"net-next" if you decide it is inappropriate for "net".

New devices will be added to the driver during the 3.6 cycle whether or
not the probing changes are accepted.  This will result in unnecessary
merge conflicts. I'll submit a new version of the patch set for
"net-next" when we have a better idea of what the device list looks like
at the beginning of the 3.7 cycle.

But I am still hoping this is accepted for "net", although I obviously
screwed up choosing strategy to avoid net/usb merge conflicts.

Ok I changed my mind and applied this to 'net'.
