Also forgot to say, all this applies for a struct platform_device,
since it is declared at compile time rather than probed by a bus and
get filled at run-time.
My understanding of the platform_device API is, that it is used for
devices, not residing on a "real" bus (like PCI, ISA with PNP, I2C,
SCSI, USB,...) and which thus cannot be really detected. Examples of such
devices, I think, are legacy ISA UARTs, could be PS/2 ports. Apart from
that platform_devices are used on various platforms where devices are
connected directly to the CPU's local bus, e.g., on many embedded
architectures.
