[DRIVER MODEL] Improved dynamically allocated platform_device interface
Re-jig the simple platform device support to allow private data
to be attached to a platform device, as well as allowing the
parent device to be set.
Example usage:
pdev = platform_device_alloc("mydev", id);
if (pdev) {
err = platform_device_add_resources(pdev, &resources,
ARRAY_SIZE(resources));
if (err == 0)
err = platform_device_add_data(pdev, &platform_data,
sizeof(platform_data));
if (err == 0)
err = platform_device_add(pdev);
} else {
err = -ENOMEM;
}
if (err)
platform_device_put(pdev);
