slip: remove dead code within the slip initialization
This following code contains a dead "if (dev).." block: ... for (i = 0; i < slip_maxdev; i++) { dev = slip_devs[i]; if (dev == NULL) break; } /* Sorry, too many, all slots in use */ if (i >= slip_maxdev) return NULL; if (dev) { sl = netdev_priv(dev); if (test_bit(SLF_INUSE, &sl->flags)) { unregister_netdevice(dev); dev = NULL; slip_devs[i] = NULL; } } ... The reason is that the code starting with "if (dev).." is never called as when we found an empty slot (dev == NULL) we break the loop and "if (dev).." not works eiter the loop ends and we get out with "i >= slip_maxdev".
