From 67c332fd12326a6ef572f07b9d71370ada6a287f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20F=C3=A4rber?= Date: Mon, 20 Aug 2012 19:08:09 +0200 Subject: [PATCH] pci: Tidy up PCI host bridges MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Adopt the QOM parent field name and enforce QOM-style access via casts. Don't just typedef PCIHostState, either use it directly or embed it.
