Subject: [net-next v2 08/15] PCI: expose pcie_link_speed and pcix_bus_speed arrays
Date: Wed, 31 Jul 2013 02:59:30 -0700 [thread overview]
Message-ID: <1375264777-13595-9-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1375264777-13595-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Jacob Keller <jacob.e.keller@intel.com>
pcie_link_speed and pcix_bus_speed are arrays used by probe.c to correctly
convert lnksta register values into the pci_bus_speed enum. These static arrays
are useful outside probe for this purpose. This patch makes these defines into
conist arrays and exposes them with an extern header in drivers/pci/pci.h
-v2-
* move extern declarations to drivers/pci/pci.h
