When trying to get the pid or card of a client, the get functions will return -1 if there is no pid or card for a client. Clients have zero or one of these, so -1 is correct for these cases. But we also need to detect the case where the kernel cannot tell us if there is a card or pid, so that userspace can fallback to probing this information in the old way.
Its a pity, that alsa-lib 1.1.1 has just been released, which just returns -1. If the time between releases is really about 2 kernel releases, you will very likely have to cope with the old API for some time.
