How a device can have "set_jack"? Isn't this part of code? Are you sure
you describe here hardware, not Linux driver behavior?

Same problems.

Additionally, if this is a type of aux-dev, then maybe it should be just
added as argument to aux-dev?

No new examples, integrate it into some existing one.
