Subject: [PATCH 4/5] powerpc/powernv: Fixup p7ioc PCIe root complex class code
Date: Mon, 7 Nov 2011 15:56:00 +1100 [thread overview]
Message-ID: <1320641761-4028-4-git-send-email-benh@kernel.crashing.org> (raw)
In-Reply-To: <1320641761-4028-1-git-send-email-benh@kernel.crashing.org>
It advertises "host bridge" instead of "PCI to PCI bridge" which confuses
the Linux probe code.
