From e3dc93be1ac46fdb58142383319b783b4c4ce8ca Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 6 Aug 2018 08:53:42 +0200 Subject: libqtest: Enable compile-time format string checking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit qtest_qmp() & friends pass their format string and variable arguments to qobject_from_vjsonf_nofail(). Unlike qobject_from_jsonv(), they aren't decorated with GCC_FMT_ATTR(). Fix that to get compile-time format string checking.
