Subject: [PATCH] arch/x86/mm/mpx.c: Clean up code by removing unnecessary assignment
Date:   Sun, 19 Jan 2020 14:09:33 +0100
Message-Id: <20200119130933.12228-1-mateusznosek0@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Mateusz Nosek <mateusznosek0@gmail.com>

Previously variable 'ret' is assigned just before return instruction.
The variable is local so this assignment is useless
and therefore can be removed.
