Sounds good.  I'll work something up.  (I'm actually thinking that
class_find_device() may be the best way to go, as it grabs a reference
to the device.)  

There should not be anything "odd" about block devices here, just do
whatever all other LED drivers do when referencing a device.

Ian, look at ledtrig-tty and maybe get inspiration from there :)
