From 931be260ed54843edac37cb3ff09a40b86114b31 Mon Sep 17 00:00:00 2001
From: Pavel Roskin <proski@gnu.org>
Date: Tue, 26 Jul 2011 22:26:59 -0400
Subject: [PATCH] ath5k: clean up base.h and its use

Remove unnecessary includes from base.h.  Add includes to other files as
necessary.  Don't include base.h unless needed.

Move declarations for functions in base.c from ath5k.h to base.h.

Use a better named define to protect base.h against double inclusion.
