+Date: Mon, 5 Jan 2009 11:01:09 +0100
+Subject: [PATCH v3 05/11] ath9k: move PCI code into separate file
-Convert 'struct pci_dev' to 'struct device' to make it usable on the AHB
-bus as well.
+Now that we have converted all bus specific routines to replaceable, we
+can move the PCI specific codes into a separate file.
