Ok will be more specific. A LED driver require to explicitly support the
trigger to run in hardware mode. The LED driver will take the
trigger_data and elaborate his struct to parse all the option
(blink_mode bitmap, interval)

So the user would be a LED driver that adds support for that specific
trigger. That is also the reason we need to export them.
