From ed4e0d2ef140aef255d67eec30767e5fcd949f58 Mon Sep 17 00:00:00 2001 From: lichun Date: Mon, 22 Jun 2020 05:30:17 +0800 Subject: [PATCH] chardev/tcp: Fix error message double free error Errors are already freed by error_report_err, so we only need to call error_free when that function is not called.
