From 84df7a50dcbed8678fdd8759858a6203889affb8 Mon Sep 17 00:00:00 2001
From: David Garske <david@wolfssl.com>
Date: Tue, 4 Jan 2022 15:38:35 -0800
Subject: [PATCH] Minor build warning fixes. Possible benchmark unused
 `bench_pq_asym_algs`. Fix if RSA enabled and `WOLFSSL_SP_MATH` set and
 `WOLFSSL_HAVE_SP_RSA` is not.
