Subject: [PULL 4/9] hmp/vnc: Fix info vnc list leak
Date: Wed, 25 Mar 2020 13:16:27 +0000 [thread overview]
Message-ID: <20200325131632.311034-5-dgilbert@redhat.com> (raw)

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
We're iterating the list, and then freeing the iteration pointer rather
than the list head.
