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

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
subsystem.
