From 2061487bdba7fb9077efc09210224b42fad7d18f Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 24 Apr 2020 10:43:37 +0200 Subject: qapi: Disallow qmp_marshal_FOO(NULL, ...) For QMP commands without arguments, gen_marshal() laboriously generates a qmp_marshal_FOO() that copes with null @args. Turns there's just one caller that passes null instead of an empty QDict. Adjust that caller, and simplify gen_marshal().
