File qtest-remove-qtest_qmp_receive_success.patch of Package qemu.20153
From: Maxim Levitsky <mlevitsk@redhat.com>
Date: Tue, 6 Oct 2020 08:59:32 -0400
Subject: qtest: remove qtest_qmp_receive_success
Git-commit: 5e34005571af53b73e4a10cb2c6e0712cf6b8d2c
References: bsc#1184574
The purpose of qtest_qmp_receive_success was mostly to process events
that arrived between the issueing of a command and the "return"
line from QMP. This is now handled by the buffering of events
that libqtest performs automatically.
