From e7b7b617689ab6fff49b16b96aa417bf2382e79b Mon Sep 17 00:00:00 2001 From: Michal Privoznik Date: Fri, 2 Nov 2018 16:12:45 +0100 Subject: [PATCH] qemuBuildInterfaceCommandLine: Reorder VIR_FREE When we have variables A, B, C then there are two ways to free them. Either in the order they are declared or the reversed one. Any other ordering is confusing. In this commit I'm reordering calls to VIR_FREE in the reversed order.
