From d2628b7d18521dacd3d4d246602e9bb3fc2a43dd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Sun, 25 Nov 2012 22:54:47 +0100 Subject: i8259: Convert PICCommonState to use QOM realizefn MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of having the parent provide PICCommonClass::init, let the children override DeviceClass::realize themselves. This pushes the responsibility of saving and calling the parent's realizefn to the children.
