I did look at using the device_id table (using USB_DEVICE_VER),
but our case is like this:

* for prodId, version 2.2 load foo_1_1.fw
* for prodId, version everything else, load foo.fw

This requires a bit of handling in the driver, hence this patch.

But thinking about it, will this work ?

USB_DEVICE_VER(vend, 0x7010, 2, 2); [set .driver_info to "foo_1_1.fw]
USB_DEVICE(vend, 0x7010); [set .driver_info to "foo.fw"]

That is, will the second registration be the fallback case in case
bcdLo and bcdHi are _anything_ other than 2.2 ?
