Please avoid drm_platform_*() usage. We're about to drop all the
drm_bus midlayers. See the tegra driver how to do it, but basically
just this:
OK, I will do it.
struct drm_device *ddev;

ddev = drm_dev_alloc(&rockchip_drm_driver, &to_platform_device(dev)->dev);
if (!ddev)
         return -ENOMEM;

r = drm_dev_set_unique(ddev, dev_name(&ddev->dev));
if (r < 0) {
         drm_dev_unref(ddev);
         return r;
}

r = drm_dev_register(ddev);
if (r < 0) {
         drm_dev_unref(ddev);
         return r;
}

+}

+static void rockchip_drm_unbind(struct device *dev)
+{
+       drm_put_dev(dev_get_drvdata(dev));
Please use:

struct drm_device *ddev = dev_get_drvdata(dev);

drm_dev_unregister(ddev);
drm_dev_unref(ddev);


Thanks
David
