From 19e3835cffbcae37ade8c3abcc4525895f7b528a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20F=C3=A4rber?= Date: Tue, 18 Jun 2013 02:23:36 +0200 Subject: [PATCH] cpu: Introduce device_class_set_vmsd() helper MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It's the equivalent to cpu_class_set_vmsd(), to assign DeviceClass::vmsd. It wasn't needed before since only static, unmigratable VMStateDescriptions were assigned so far.
