The most obvious response is that this needs to be broken up into
multiple patches.

I think I liked almost all the comments...

To me it seems useful to know that we're talking about the power supply.

Adding _REG to the name seems not terribly useful and it makes the name
longer so we're going to run into the 80 character limit.  I just
checked and this patch does add some checkpatch warnings.

But aligning the arguments is fine, deleting unused macros is fine,
adding blank lines is fine.

Making this reverse Christmas tree is fine.  But these things should all
be done in separate patches.
