I think part of the confusion is that this is what in other subsystems
is called a device, not a client. I believe I'm still confused in the
same way that Greg is.

You already have a 'struct mei_device', which refers to the PCI device
that owns the bus, and has clients attached to it. While it may be
a little confusing to people that already worked with the current
mei code, I think it would help to rename the existing 'mei_device'
to 'mei_host' or something else that feels appropriate, and introduce
the new structure as 'mei_device' derived from 'struct device', again
matching what most other subsystems do.

Similarly, you can then rename 'mei_bus_driver' to 'mei_driver' to fit
that logic, since I would consider a 'bus_driver' to be something
that is responsible for the entire bus, not just for one device.
