Message-Id: <abc11d127dbde89baf98eaa6c409d89b2a8a5a21.1304970062.git.joe@perches.com>
Date: Mon, 9 May 2011 12:45:20 -0700
From: Joe Perches <joe@...ches.com>
To: Grant Grundler <grundler@...isc-linux.org>
Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH net-next 1/4] tulip: xircom_cb: Convert #ifdef DEBUG blocks and enter/leave uses
Change the blocks that are guarded by #if DEBUG to
be #if defined DEBUG && DEBUG > 1 so that pr_debug
can be used later.
Remove enter/leave macros and uses.
