kobject: kobj->k_name verification fix
The function 'kobject_add' tries to verify the name of a new kobject instance is properly set before continuing. 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; } The statement: if (!kobj->k_name) { pr_debug("kobject attempted to be registered with no name!\n"); WARN_ON(1); return -EINVAL; } is useless the way it is right now, because it can never be true. I think the code was intended to be: 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; } because this would make sure the kobj->name buffer has something in it. So the missing '*' is just a typo. Although, I would much prefer expression like: if (*kobj->k_name == '\0') { pr_debug("kobject attempted to be registered with no name!\n"); WARN_ON(1); return -EINVAL; } because this would've made the intention clear, in this patch I just restore the missing '*' without changing the coding style of the function.
