I wonder if the kernel should actually return -EINVAL for that one. Oh
well, probably not much point in trying to change it now and risk
something breaking.
Hmm. Actually the kernel now does
radix_tree_lookup(&idr->idr_rt, id - idr->idr_base);
which looks a bit suspicious for the id < idr_base case. I don't think
we use idr_base for kms stuff yet though, but we do for gem.
Anyways test looks all right to me
