I was wondering if, instead of calling put_device() only on non-ACPI systems, 
would it be better if on an ACPI system I called get_device() manually?  That 
is, some thing like this:

int emac_phy_config(struct platform_device *pdev, struct emac_adapter *adpt)
{
...
	if (has_acpi_companion(&pdev->dev)) {
...
		get_device(&mii_bus->dev);
	} else {
...
