Message-Id: <1fbe5c552df39789d6df62e381fe4cac63630808.1264541549.git.joe@perches.com>
Date: Tue, 26 Jan 2010 13:40:09 -0800
From: Joe Perches <joe@...ches.com>
To: "David S. Miller" <davem@...emloft.net>
Cc: netdev@...r.kernel.org
Subject: [PATCH 10/21] net/atm/mpc.c: checkpatch cleanups
Convert #include <asm... to #include <linux...
Add printk argument verification to dprintk and ddprintk
Spacing cleanups
Mostly 80 column wrapped.
printk->pr_info and pr_cont
Moved labels to column 1
Move trailing statements to new lines
switch/case cleanups
remove unnecessary breaks after returns
Remove unnecessary braces around single line statements
