This means that the CODEC will no longer be held in reset (which
presumably has a power benefit or something) even if jack detection
isn't in use. What most devices do is have things like this be
controlled via the bias level or other power management functions and
then have jack detection hold the CODEC out of the lowest power states
when it's active.
