Should we not do the usb_put_dev() before the free_netdev()?

Why?  The usb_put_dev() doesn't really do anything, except for the fact
that you have to do it because you did a usb_get_dev() earlier.

More that the dev-> dereference may be invalid at that point, since the
netdev (and hence dev) has been free_netdev()-ed.

Cheers,
