As I said in reply to your earlier mail the pre-existing code in the
driver already does that:

--- a/sound/soc/s3c24xx/smdk_wm9713.c
+++ b/sound/soc/s3c24xx/smdk_wm9713.c
@@ -95,6 +95,7 @@ err:
 static void __exit smdk_exit(void)

This preexisting line from the context is cleaning up the soc-audio

+       platform_device_unregister(smdk_snd_wm9713_device);

This new line cleans up the wm9713-codec device which is also added in
the probe function (yay AC'97!).

Reloading the module works, I've been doing that rather a lot.
