From 64e1062b2371cb8d6126d4e970832365a1a84562 Mon Sep 17 00:00:00 2001
From: Christian Lamparter <chunkeey@gmail.com>
Date: Wed, 4 Oct 2017 01:00:12 +0200
Subject: [PATCH 20/25] crypto: crypto4xx - fix various warnings
crypto4xx_core.c:179:6: warning: symbol 'crypto4xx_free_state_record'
was not declared. Should it be static?
crypto4xx_core.c:331:5: warning: symbol 'crypto4xx_get_n_gd'
was not declared. Should it be static?
crypto4xx_core.c:652:6: warning: symbol 'crypto4xx_return_pd'
was not declared. Should it be static?
crypto4xx_return_pd() is not used by anything. Therefore it is removed.
