ionic: prevent early watchdog check In one corner case scenario, the driver device lif setup can get delayed such that the ionic_watchdog_cb() timer goes off before the ionic->lif is set, thus causing a NULL pointer panic. We catch the problem by checking for a NULL lif just a little earlier in the callback. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
