"Jack" seems to be an internal jargon that many people won't recognize.
It's, in fact, 3.5-pi, isn't it?

Anyway, this is already being used as an enum with drivers,
I'd suggest to add a comment in extcon.h stating that 
"Jack connector" is usually the 3.5-pi earbud connector.

Anyway, I like the direction of this patch.
