Subject: [PATCH] Staging: comedi: addi-data: remove unnecessary variable initializations in hwdrv_apci035.c
Date: Fri, 28 Feb 2014 01:30:45 -0600
Message-Id: <1393572645-9470-1-git-send-email-chase.southwood@yahoo.com>
Sender: linux-kernel-owner@vger.kernel.org

Nearly every variable in hwdrv_apci035.c is initialized to 0 when it is
declared, and then set to some other value before ever being used.  As
such, we can remove all of these initializations.  They are accomplishing
nothing.
