But more importantly the user of the sysfs files is the right place
the just check for these values being non-present.  As said before
it's perfectly valid for 1.0 devices so they have to cope with it
anyway.  I don't think a message in the kernel log that is very to
process algorithmically is not very useful.

(I really with we'd have useful and required identifiers from the
start, but that's a separate discussion)
