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.
