kobject_add unreachable code

From: Martin Stoilov

The following code in kobject_add
if (!kobj->k_name)
kobj->k_name = kobj->name;
if (!kobj->k_name) {
pr_debug("kobject attempted to be registered with no name!\n");
WARN_ON(1);
return -EINVAL;
}

doesn't look right to me. The second 'if' statement looks useless after
the assignment in the first one. May be it was meant to be like:
if (!*kobj->k_name)
