Message-Id: <1339339147-24743-2-git-send-email-geert@linux-m68k.org>
Date: Sun, 10 Jun 2012 16:39:07 +0200
From: Geert Uytterhoeven <geert@...ux-m68k.org>
To: Yoshinori Sato <ysato@...rs.sourceforge.jp>,
Andrew Morton <akpm@...ux-foundation.org>
Cc: linux-kernel@...r.kernel.org,
Geert Uytterhoeven <geert@...ux-m68k.org>
Subject: [PATCH 2/2] h8300: Use the declarations provided by <asm/sections.h>
- Include <asm/sections.h>,
- Remove the (different) extern declarations,
- Remove the no longer needed address-of ('&') operators,
- Remove the superfluous casts, use proper printk formatting instead.
Signed-off-by: Geert Uytterhoeven <geert@...ux-m68k.org>
