Subject: ensure NULL deref can't possibly happen in is_exported()
From: Jesper Juhl <jesper.juhl@xxxxxxxxx>
If CONFIG_KALLSYMS is defined and if it should happen that is_exported() is
given a NULL 'mod' and lookup_symbol(name, __start___ksymtab,
__stop___ksymtab) returns 0, then we'll end up dereferencing a NULL
pointer.
