Bullshit.

This is a regression, and it needs to be fixed. The "device needs
power" crap is just that - crap. Nobody cares. OF COURSE all devices
need power, but that is totally irrelevant for a driver. The SSD in my
system "needs power", but I have absolutely zero regulator information
for it NOR DO I F*CKING NEED ANY!

Claiming that we need to know the power regulator for an accelerometer
is total utter idiocy and crap.

I'm going to revert that commit unless you can fix it some other way
(dummy regulators when you can't find a real one or whatever). The
notion that you have to have regulator information in order to use
some random device is insanity. I don't understand how you can even
start to make excuses like that. It's so obviously bogus that it's not
even funny.

Why do I have to explain the "no regressions" to long-time kernel
maintainers EVERY SINGLE RELEASE? What the f*ck is *wrong* with you
people? Seriously?
