AFAIK, the only LED trigger that does anything similar is the netdev
trigger.  It uses dev_get_by_name(), which is specific to network

The block subsystem doesn't appear to have any similar API, which is
why Enzo submitted his patch to export block_class and disk_type back
in April[1], when he wanted to do something similar.

I'm basically bypassing the need to export the symbols, because my
trigger code is actually in the block subsystem, rather than the LEDs
