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".
