interrupt, making it possible for audio applications to monitor changes
in the hardware.

I would cache the pointer to snd_kcontrol structure in spdif_priv. This lookup
is expensive for the interrupt routine in my eyes.

Thanks! Sorry for a bit late answer, but submitted new patch few days
ago with fix for this and the other remarks.

Thanks! Sorry for a bit late answer, but re-worked solution submitted
few days ago where caching as you suggest is implemented.
