It's not meaningful or sensible to have a pin switch and jack detection
connected to the same pin, any machine driver doing that is buggy.  It's
unclear how the two would be supposed to interact and there's nothing
that makes an effort to keep them in sync.  Either jack detection should
be disconnected from DAPM and userspace responsible for managing the
paths via the pin switches or the pin switches should be removed.
