Message-Id: <1424901403-6458-1-git-send-email-ameenali023@gmail.com> Date: Wed, 25 Feb 2015 23:56:43 +0200 From: Ameen Ali <ameenali023@...il.com> To: shahed.shaikh@...gic.com, Dept-GELinuxNICDev@...gic.com Cc: linux-kernel@...r.kernel.org, netdev@...r.kernel.org, Ameen Ali <ameenali023@...il.com> Subject: [PATCH 6/6] qlcnic_dcb.c : possible division by zero. Whenever there is a division it is usually worthwhile to add some belt'n'braces code to ensure that cnt != 0, otherwise a machine signal can occur.
