From 92558d67a463bfbb351d30e28648de03b635f024 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 6 Sep 2007 16:27:37 +0000 Subject: strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX__ becomes CONFIG_TARGET_, same for profiles. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@8653 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- target/linux/ar7/files/drivers/leds/leds-ar7.c | 132 +++++++++++++++++++++++++ 1 file changed, 132 insertions(+) create mode 100644 target/linux/ar7/files/drivers/leds/leds-ar7.c (limited to 'target/linux/ar7/files/drivers/leds/leds-ar7.c') diff --git a/target/linux/ar7/files/drivers/leds/leds-ar7.c b/target/linux/ar7/files/drivers/leds/leds-ar7.c new file mode 100644 index 0000000000..85533dee12 --- /dev/null +++ b/target/linux/ar7/files/drivers/leds/leds-ar7.c @@ -0,0 +1,132 @@ +/* + * linux/drivers/leds/leds-ar7.c + * + * Copyright (C) 2007 OpenWrt.org + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
