I don't really understand why there can only be up to 10 characters in
the module part number. I also don't understand why you wrote "20
bytes (10 chars)" for this in the previous patch. Are you assuming
that module part numbers are UTF16LE? According to my reading of the
spec, it sounds like they're supposed to be plain ASCII, i.e. 20 bytes
should be able to contain up to 20 chars.
