[Qemu-devel] [PULL 14/21] monitor: Limit QError use to command handlers


From: Markus Armbruster
Subject: [Qemu-devel] [PULL 14/21] monitor: Limit QError use to command handlers
Date: Tue, 2 Jun 2015 10:23:52 +0200

The previous commits narrowed use of QError to handle_qmp_command()
and its helpers monitor_protocol_emitter(), build_qmp_error_dict().
Narrow it further to just the command handler call: instead of
converting Error to QError throughout handle_qmp_command(), convert
the QError gotten from the command handler to Error, and switch the
helpers from QError to Error.
