From c0f26a13c6ddd9aca729012d3a31347f77d52c68 Mon Sep 17 00:00:00 2001 Message-Id: From: John Ferlan Date: Mon, 17 Dec 2018 20:42:32 -0500 Subject: [PATCH] qemu: Alter @val usage in qemuSetUnprivSGIO MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit https://bugzilla.redhat.com/show_bug.cgi?id=1656362 (RHEL8) https://bugzilla.redhat.com/show_bug.cgi?id=1656360 (RHEL7) RHEL-only Rather than initializing to -1 and then setting to the result of a boolean check (either 0 or 1), let's just initialize @val to 0 and then only change to 1 if conditions are "right".
