From 3ed439c56e0d82fd08275fff2c21278f92ed8ec5 Mon Sep 17 00:00:00 2001 From: Catherine Sullivan Date: Wed, 13 Apr 2016 03:08:27 -0700 Subject: [PATCH] i40e: Fix uninitialized variable 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.
