Message-Id: <b18a29f3f4217c311ff672a4ffb0bdadd2f6930d.1324246975.git.joe@perches.com>
Date: Sun, 18 Dec 2011 14:23:40 -0800
From: Joe Perches <joe@...ches.com>
To: Matt Mackall <mpm@...enic.com>,
Herbert Xu <herbert@...dor.apana.org.au>,
"David S. Miller" <davem@...emloft.net>
Cc: linux-kernel@...r.kernel.org, linux-crypto@...r.kernel.org
Subject: [PATCH 1/2] crypto: Remove global #define PFX and use, use pr_<level>
PFX is not a good #define to have in a system #include.
Use pr_fmt and pr_<level> instead.
Signed-off-by: Joe Perches <joe@...ches.com>
