From 5e7bcb74706e6398ea582001fe025e6eb0c5c998 Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>
Date: Fri, 2 Jan 2009 16:10:55 +0100
Subject: [RFC 06/12] ath9k: convert to struct device
Now that we have converted all bus specific routines to replaceable, we
can move the PCI specific codes into a separate file.
