I prefer GPIO stuff built in conditionally. The jack layer is used also for non-ASoC codes, and GPIO isn't always present.

This is the jack wrapper in sound/soc rather in the generic sound/core version so it should be safe to have it in unconditionally (I'd be surprised if an ASoC platform didn't have gpiolib support), though there's no harm in making it conditional on gpiolib either.
