When both an SPDIF and an HDMI output are present on HD-audio, both try to access IEC958 controls with index=0 although one of them must be wrong. For avoiding this conflict, the recent kernel code moves the IEC958 controls of an SPDIF with device=1 once when the conflict happens.
In this patch, the corresponding support is added in alsa-lib side. The new "skip_rest" boolean flag is added to the hooked element definition which indicates that the rest of element array will be ignored once when this element is present and evaluated. With this new flag, the HD-audio config takes device=1 primarily, then take device=0 as fallback.

AFAICS this patch was never applied. Was there a reason for that?
