[Qemu-devel] [PATCH 13/30] qdev: add class_init to DeviceInfo

[Anthony Liguori <aliguori@us.ibm.com>]

Since we are still dynamically creating TypeInfo, we need to chain the
class_init function in order to be able to make use of it within subclasses of
TYPE_DEVICE.

This will disappear once we register TypeInfos directly.
