Please fix the description as mentioned in other patches.
The code change is fine, but it does raise the question of whether we want to think
about providing a means to register such devices using the of_match_table.
It's somewhat irritating to need to provide both (I'd rather not
just provide the non-dt version rely on the old hack that drops the
vendor ID for matching).
