From ce6a28ee057da3e4a587dada369e33a8486b0066 Mon Sep 17 00:00:00 2001 From: Marcel Apfelbaum Date: Tue, 2 Jun 2015 14:22:57 +0300 Subject: hw/pci: made pci_bus_is_root a PCIBusClass method Refactoring it as a method of PCIBusClass will allow different implementations for subclasses. Removed the assumption that the root bus does not have a parent device because is specific only to the default class implementation. Signed-off-by: Marcel Apfelbaum Reviewed-by: Michael S.
