Of course, if it isn't public, I assume it hasn't actually been signed by anybody, which makes it largely useless. But any future signing action will validate the pre-signing uses of the key, so that's fixable.
We have a Linaro meeting this week, so we will make sure to get this key and other relevant ones signed by everyone who is here and in the kernel keyring.
