You have a 200 mA system load on this regulator? I guess this is a
workaround for drivers that don't set the load properly themselves?
I wonder if there is a bug in my patch where the system load doesn't
take effect if nobody ever calls set_load. Let's see... Does the
below fix things for you? It's totally untested and whitespace
damaged but I wanted to get a response out quick and I'm just walking
out the door. I'll test more / dig more either tonight or at work
tomorrow:
