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.
