[libvirt] [PATCH] pci.c: correct erroneous expression

An expression like this, can never be true, since the RHS is nonzero: ... !pciRead16(dev, PCI_CLASS_DEVICE) == PCI_CLASS_BRIDGE_PCI) This appears to be what was intended: pciRead16(dev, PCI_CLASS_DEVICE) != PCI_CLASS_BRIDGE_PCI) From: Jim Meyering <meyering(a)redhat.com&gt; Date: Tue, 26 Jan 2010 20:36:58 +0100 Subject: [PATCH] pci.c: correct erroneous expression * src/util/pci.c (pciDeviceDownstreamLacksACS): Fix a typo that rendered a subexpression always false. --- src/util/pci.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/util/pci.c b/src/util/pci.c index 09535bd..0274806 100644 --- a/src/util/pci.c +++ b/src/util/pci.c @@ -1,5 +1,5 @@ /* - * Copyright (C) 2009 Red Hat, Inc. + * Copyright (C) 2009-2010 Red Hat, Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -1266,7 +1266,7 @@ pciDeviceDownstreamLacksACS(virConnectPtr conn, return -1; pos = dev->pcie_cap_pos; - if (!pos || !pciRead16(dev, PCI_CLASS_DEVICE) == PCI_CLASS_BRIDGE_PCI) + if (!pos || pciRead16(dev, PCI_CLASS_DEVICE) != PCI_CLASS_BRIDGE_PCI) return 0; flags = pciRead16(dev, pos + PCI_EXP_FLAGS); -- 1.7.0.rc0.140.gfbe7
