Message-ID: <20091006213344.4272.61588.stgit@bob.kio>
Date: Tue, 06 Oct 2009 15:33:44 -0600
From: Bjorn Helgaas <bjorn.helgaas@...com>
To: Jesse Barnes <jbarnes@...tuousgeek.org>
Cc: linux-pci@...r.kernel.org, linux-kernel@...r.kernel.org,

Subject: [PATCH 4/7] PCI: print resources consistently with %pRt
This uses %pRt to print additional resource information (type, size,
prefetchability, etc.) consistently.
