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.
