Use the control interface (field 'components' in the info structure)
to pass the I/O configuration details. The long card name might
be used in GUI. This information should be hidden.

If this is at the board level, then maybe move this to
sound/soc/intel/boards/Kconfig
I am not sure about the alsa-lib dependency, it's a bit odd, isn't it?
shouldn't this be handled via protocol versions? or a configuration
provided by alsa-lib somehow?
It's not about the protocol. It's about to move this type of information to
another place. I can remove the ALSA version sentence from the help, because
it's just a hint. I would like to create ucm2 configurations based on this
rather than the misused long card names.
