Date: Sun, 28 Feb 2010 17:01:13 +0000 Message-Id: <1267376473-9204-1-git-send-email-gurligebis@gentoo.org> X-Mailer: git-send-email 1.7.0 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 4227 Lines: 152 LED driver for the Soekris net5501 board. It is based on the previously submitted code by Alessandro Zummo, but is changed to use the new GPIO driver with 2.6.33, and the driver has been moved to drivers/leds where it belongs.
