From 2897ae026758eac78284ba6c3bd7732f3a1d9987 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 5 Feb 2014 16:36:48 +0100 Subject: [PATCH] qdev:pci: refactor PCIDevice to use generic "hotpluggable" property Get rid of PCIDevice specific PCIDeviceClass.no_hotplug and use generic DeviceClass.hotpluggable field instead.
