From c01e68853148764d32c3a27ab4b39cb553c567fc Mon Sep 17 00:00:00 2001 From: Luiz Capitulino Date: Mon, 22 Nov 2010 16:22:47 -0200 Subject: QMP: Fix default response regression Commit 030db6e89d dropped do_info() usage from QMP and introduced qmp_call_query_cmd(). However, the new function doesn't emit QMP's default OK response when the handler doesn't return data. Fix that by also calling monitor_protocol_emitter() when ret_data == NULL, so that the default response is emitted.

Just drop it.
