These patches implement UAC2 jack detection.
This allows USB-to-3.5mm adapters and similar USB devices to report jack state via alsa control, using the reporting provided by the UAC2 connector control.
The second patch updates the clock validity control so it doesn't show up in mixer UIs.
I declined to mark the controls as VOLATILE since clients should always be notified of changes, since UAC devices are expected to generate interrupt messages when a control value changes.
Right, after consideration, I concluded that, too. Sorry for confusion.
