Please submit patches using subject lines reflecting the style for the

I'm not sure this is something we want to support at all, I can't
immediately see anything that does this deliberately in the SPI code and
obviously the "bus number" is something of a Linux specific concept
which would need some explanation if we were going to document it.  It's
something I'm struggling a bit to see a robust use case for that isn't
better served by parsing sysfs, what's the goal here?

This is definitely *not* trivial but yes, in general you should CC
maintainers on things.
