For instance, drivers/net/wireless/atmel.c looks very similar, so I guess it has the same race. With airo the race is just more visible, because of all the long sleeps it does between getting the name with dev_alloc_name and finally registering it. eepro100.c takes rtnl_lock to avoid the issue. So does ns83820.c - it has a big comment about how ugly it is.
