From 395a22fae064df64d987d703cf70ae0f57306be8 Mon Sep 17 00:00:00 2001 From: Jeff Cody Date: Thu, 22 Jan 2015 08:03:25 -0500 Subject: [PATCH] block: vmdk - make ret variable usage clear Keep the variable 'ret' something that is returned by the function it is defined in. For the return value of 'sscanf', use a more meaningful variable name.
