As this was already submitted this should probably say [PATCH V2] in the
subject.

And put a change log here, ie.:

V2:
 - add de...@driverdev.osuosl.org

You could have changed it to 'const char dev_name[] = "wlan0";'.

First of all. Why using a memcmp here? dev_iface->ifa_label could be
shorter. Also using the value '5' here is tricky. So it would be better
to say:

                if (strlen(dev_iface->ifa_label) == strlen(dev_name) &&
                    memcmp(dev_iface->ifa_label,
                           dev_name, strlen(dev_name)) == 0)

However, it does not make sense at all to compare with wlan0 in the
first place. The net_device is registered in wilc_netdev_init() with
"wlan%d" as it should so there is no guarantee it is wlan0.
