From: Eliot Blennerhassett eblennerhassett@audioscience.com
Structs hpi_adapter and snd_card_asihpi had members that duplicate those in underlying hpi_adapter_obj or whose info can be retrieved using hpi_adapter_get_info().
Print less info in probe function, it can be retrieved from /proc.
Avoid name redundancy: hpi_adapter_obj.adapter_type renamed to .type
