Ah, I remember this old one. We discussed this with upstream and found
the issue was that for that specific firmware, the clm-blob was included
in the firmware blob itself, but the code that loaded firmware blobs
still warned that it couldn't find the external file. That code was
eventually cleaned up so it no longer complains, so this is essentially
fix released.
