commit 5c219a340850233aecbb444af964653ecd3d1370 upstream.

HD-audio core code replaces the kctl->id.index of SPDIF-related
controls after assigning via snd_ctl_add().  This doesn't work any
longer with the new Xarray lookup change.  The change of the kctl->id
content has to be done via snd_ctl_rename_id() helper, instead.

Fixes: c27e1efb61c5 ("ALSA: control: Use xarray for faster lookups")
