From 41725fa7eda1d97576fc8c79b58d04a61629f40e Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Mon, 5 Oct 2020 17:58:47 +0200 Subject: qmp: Call monitor_set_cur() only in qmp_dispatch() The correct way to set the current monitor for a coroutine handler will be different than for a blocking handler, so monitor_set_cur() needs to be called in qmp_dispatch().
