Hi Yuan
And where do you put the bus name? The bus operations? The mutex for
accessing devices on the bus? The bus is a device, so you need a
device structure somewhere, to make it part of the device
hierarchy. Where do you put that?
I think it is time to stop this discussion, and you need to submit
patches we can review, how you think this would work. That will make
you look at the details.
