vfio/mdev is the last user of class_compat, and it doesn't use it for the intended purpose. See kdoc of class_compat_register(): Compatibility class are meant as a temporary user-space compatibility workaround when converting a family of class devices to a bus devices. In addition it uses only a part of the class_compat functionality. So inline the needed functionality, and afterwards all class_compat code can be removed.
