From 844bd70b5652f30bbace89499f513e3fbbb6457a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Thu, 4 Jun 2020 11:44:25 +0200 Subject: [PATCH] qga: fix assert regression on guest-shutdown MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit 781f2b3d1e ("qga: process_event() simplification"), send_response() is called unconditionally, but will assert when "rsp" is NULL. This may happen with QCO_NO_SUCCESS_RESP commands, such as "guest-shutdown".
