I wouldn't disagree if you made this dev_err() instead of
dev_warn(). The reasoning behind is that if it's a warning you
should not fail. But beacuse you are returning -EINVAL it means
that you are failing, therefore you should use dev_err().
Others might object that the change I'm suggesting sohuld go in a
different patch, which is also OK.

... or, if you want to keep the dev_warn(), whou can consider
removing the "return -EINVAL;". But this is an evaluation you
should make in a different patch and mainly evaluate if it's
OK to remove the error here.

Nothing wrong with the patch itself. But imagine if we end up in
one of those printouts and, as a user, you read something like:
... vme_slot_num not supported
The message itself doesn't say much to the user. The perfect fix
would be to re-write all these error messages with a proper
meaningful sentence, like, e.g.:
Can't retrieve the CS/CSR slot id
(don't even know if it's fully correct). Anyway, I understand
you don't have much time for such fine changes, so whatever you
decide to do:
