[alsa-devel] ALSA: hda: hdmi: Hint matching between input devices and pcm devices

Since modern HDMI cards often have more than one output pin and thus input device, we need to know which one has actually been plugged in.

This patch adds a name hint that indicates which PCM device is connected to which pin.

To do that, the jack creation has been deferred to build_controls, i e, after the PCM devices have been created.

Would be great to have Stephen look through this patch quickly before it's committed.
