From: Arnd Bergmann arnd@arndb.de
Along the same lines as making devm_led_classdev_register() declared extern unconditional, do the same thing for the two sub-classes that have similar stubs.
The users of these interfaces go to great lengths to allow building with both the generic leds API and the extended version, but realistically there is not much use in this, so just simplify it to always rely on it and remove the confusing fallback logic.
