Message-Id: <1462147581-135254-7-git-send-email-jeffrey.t.kirsher@intel.com> Date: Sun, 1 May 2016 17:06:12 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Catherine Sullivan <catherine.sullivan@...el.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next 06/15] i40e: Fix uninitialized variable From: Catherine Sullivan <catherine.sullivan@...el.com> We have an uninitialized variable warning for valid_len for one case in validate_vf_mesg. To fix this, just initialize it to 0 at the top of the function and remove all of the now redundant assignments to 0 in the individual cases.
