Do we still need InlineLoc parameter in ParseInnerNamespace method?

Hi all!
In ParseInnerNamespace method, the InlineLoc seems to be useless.
Compiler doesn't warn about this case because its formally used in recursive call.
Looks like InnerNSs[index].InlineLoc are used instead. While InlineLoc itself has been used during in parent ParseNamespace method, during NamespaceDecl creation.

So now it seems to be a case:

void Foo(bool someCondition, int useless) {
  if (someCondition)
    Foo(someCondition, useless);

So, is here any reason to keep InlineLoc?
P.S.: This is non-const reference by the way.
