[alsa-devel] [PATCH 13/21] Remove redundant struct members.
linux at audioscience.com
linux at audioscience.com
Thu Dec 22 01:38:43 CET 2011
From: Eliot Blennerhassett <eblennerhassett at 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
