Current non-GPL users of led_set_brightness would be affected if we
changed this. I am not however certain if there are any, having in mind
that led_classdev_register is exported with EXPORT_SYMBOL_GPL.
Theoretically it is possible to use led_set_brightness without
registering LED class device, but it would be partially broken then
due to not initialized set_brightness_work.
I think that it would be safe to apply this patch.
I need acks, though :)
