The code in question is below.  Is this missing an assignment to n
in the else branch?

static inline unsigned long __must_check copy_from_user(void *to,
                                          const void __user *from,
                                          unsigned long n)
{
        int sz = __compiletime_object_size(to);

        if (likely(sz == -1 || sz >= n))
                n = _copy_from_user(to, from, n);
        else
                copy_from_user_overflow();

        return n;
}
