It's not good etiquette to send patches 'From:' and 'Signed-off-by:' a
person when they are neither from or signed-off by that person.
It's much better practice to reply to the original patches with
comments placed directly under the code you wish to reference.

So what happened to these?

I'm not a big fan of this.

I see where you're going with this, but my personal opinion is that it
looks neater and more readable set out as two separate init functions.

Great spot Micky. I'll fix this up and resend.
