The userspace consumer.

I don't know what you're trying to do or why, nor how you're going about
achieving it so I can't really comment.  Like I say anything that's
instantiating a userspace consumer in upstream code is broken, it's
there for test during development of regulator drivers.  Whatever device
is supplied by the regulator should have a driver which should control
the regulator at runtime if that is needed.
