Which is OK.

If you're a user, you can't fix the problem by yourself and spamming the
logs with continued warnings doesn't help here.

If you're a developer, you'll fix the first driver and then see the
warning from the second one.

First, I've applied your patch already.  Second, I really think that
WARN_ON_ONCE() is better here.
