Subject: [PATCH] staging: rtl8723au: core: rtw_security: Removed variables that is never used
Date: Sat, 31 Jan 2015 16:03:20 +0100
Message-Id: <1422716600-4498-1-git-send-email-rickard_strandqvist@spectrumdigital.se> (sfid-20150131_160025_333799_2830E070)
Sender: linux-wireless-owner@vger.kernel.org
List-ID: <linux-wireless.vger.kernel.org>

Variable was assigned a value that was never used.
I have also removed all the code that thereby serves no purpose.

This was found using a static code analysis program called cppcheck
