Done. (Sent as separate email not part of this thread.)

I have not made progress concerning the reduced logic in '.reset'.
I will not attempt this any further as I do not have the right circumstances
to test this properly.

This is still an open question to me: from what I can tell,
'brcmfmac43456-sdio.clm_blob' loads correctly even though the macro
does not define it. So this may concern certain specific use cases.
