Subject: qdev: add class_init to DeviceInfo
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3dde52d2fe5fd4783bdd06f88561cbd0695aae06;p=qemu.git

qdev: add class_init to DeviceInfo

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.
