You are a bit confused here.  device_t is a _pointer_ to the struct
device, not inline struct device (as it used to be).  You can check
cvs history for commits that (among other things) do:

-	struct device foo_dev;
+	device_t foo_dev;

usually with something like "split softc and device_t" in the log
message.
