   4 Subject: [PATCH] [led] Misc fixes in the driver code
   5      to_bundle returned the wrong data. The platform_device is the
   6      parent of the class_device used by the LED device class. Return
   7      the correct class.
   8
   9     num_leds was not set to the correct number of registered LEDs. All
  10     loops using num_leds (e.g. module unloading) were not executed at
  11     all.
  12
  13     On removal of the module disable all LEDs.
