That helps but in that case you also need to remove all the device
registration stuff except for the actual machine driver from the init
and exit functions. The CPU stuff is all a fixed property of the CPU
and should be reigstered by the architecture code (possibly with some
control for the individual machine), the CODEC should be being
enumerated by whatever normally does that. The only thing this driver
should be doing is specifying how these things are connected.

What exactly is the msic CODEC? Given the references to non-specific
"vendor" registers it doesn't sound like a particular CODEC driver.
