We've been through this repeatedly - this is the case for all probe
deferrals and if we just don't print the errors at all then people won't
be able to tell if they've got a missing dependency.  We need people to
work on things like allowing the kernel to make use of the dependency
information it has to order probes more sensibly.

Raphael had some ideas he was talking about at Kernel Summit for this,
Russell King also proposed just suppressing the errors until we're at
the last deferred probe run at the end of init.
