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;
}
