Yup, that would be nice. I guess a real-life example where it makes a
big different would help with lobbying such a change into mainline.

An incremental way to implement this would be to make a driver-specific
function for asynchronous requests, and maybe have some fiendishly
inefficient generic fallback. That way one driver could be changed at a
time, without having to redesign the SPI core.
