+From 2dc4f2819aec1cdd3012cb28396a625d2efb00fd Mon Sep 17 00:00:00 2001
+From: Cesar Eduardo Barros <cesarb@cesarb.net>
+Date: Mon, 4 Aug 2008 08:34:50 +0100
+Subject: [PATCH] device model: Allow the creation of symlinks on /sys/bus/*/devices
+
+Allows the direct creation of symlinks on /sys/bus/*/devices. This is needed
+for a compat symlink from gta01-pm-gps.0 to neo1973-pm-gps.0 on the Openmoko
+Neo1973 GTA01.
