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.
