Hi Christophe,

I do not see why it is weird. request_region() gives you an instance of
"resource" structure which can later be freed. If we indeed want to use
release_region() (and hardcode the length in both places) then we should
also remove gp->res_port member. But I really do not find anything wrong
nor do I want to touch these old drivers...

Thanks.
