+From 28b29382f1f9c4f6783054527283a8247b2c5cba Mon Sep 17 00:00:00 2001
+From: Holger Freyther <zecke@openmoko.org>
+Date: Fri, 25 Jul 2008 23:06:05 +0100
+Subject: [PATCH] [led] Misc fixes in the driver code
+ to_bundle returned the wrong data. The platform_device is the
+ parent of the class_device used by the LED device class. Return
+ the correct class.
+
+ num_leds was not set to the correct number of registered LEDs. All
+ loops using num_leds (e.g. module unloading) were not executed at
+ all.
+
+ On removal of the module disable all LEDs.
