I do object to using V4L2 async. It's designed for independent
components of media pipelines, handled by multiple different drivers
and also modelled as V4L2 subdevices. We don't have anything like that
here.

How about just open coding something trivial that only fits the needs
of this specific driver? I think it would be as simple as a linked
list and registering the V4L2 devices only after all the nodes probe.

Best regards,
Tomasz
