Calling\nput_device(&mdev->dev) there triggers a device core WARN and ends up\ninvoking kref_put(&kobj->kref, kobject_release) on an uninitialized\nkobject.\n\nIn this path the private struct was only kmalloc'ed and the intended\nrelease is effectively kfree(mdev) anyway, so free it directly instead\nof calling put_device() on an uninitialized device.\n\nThis removes the WARNING and fixes the pre-initialization error path."
