ALSA: asihpi - Remove redundant struct members.
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 Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
