[Qemu-devel] [PULL 07/96] pci: Permit incremental conversion of device models to realize |
Date: |

From: Markus Armbruster <address@hidden>
Call the new PCIDeviceClass method realize(). Default it to
pci_default_realize(), which calls old method init().
To convert a device model, make it implement realize() rather than
init().
