The same argument would apply to commits
e1e499eef2200c2a7120c9ebf297d48b195cf887 and
while they made it into the upstream kernel.

So I would think that such a change should be ok for a next release,
but without backport to stable branches.

Would it be possible to add some autodetection for known devices,
in a similar way the cdc_ether driver does it.

It's really strange that Ericsson F3507g and Ericsson F5521gw appear as
different kind of devices, while using the same kernel version.

And Ericsson F3507g already changed from usbX to wwanX between 2.6.32
(ubuntu 10.04)
and 2.6.38 (ubuntu 11.04).
