Subject: [PATCH v3 8/8] hw/misc/vmcoreinfo: Add comment about reset handler
Date: Thu, 10 Oct 2019 15:15:27 +0200 [thread overview]
Message-ID: <20191010131527.32513-9-philmd@redhat.com> (raw)
In-Reply-To: <20191010131527.32513-1-philmd@redhat.com>
The VM coreinfo device does not sit on a bus, so it won't be
reset automatically. This is why it calls qemu_register_reset().
Add a comment about it, so we don't convert its reset handler
to a DeviceReset method.
