From 7036b92d303a01477e27a5a9b2d582a5df3cc8ef Mon Sep 17 00:00:00 2001 From: Eliot Blennerhassett Date: Thu, 22 Dec 2011 13:38:43 +1300 Subject: 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 Signed-off-by: Takashi Iwai --- sound/pci/asihpi/asihpi.c | 143 +++++++++++++++++++++------------------------ sound/pci/asihpi/hpi6000.c | 59 +++++++++---------- sound/pci/asihpi/hpi6205.c | 8 +-- sound/pci/asihpi/hpicmn.c | 20 +++---- sound/pci/asihpi/hpicmn.h | 11 ++-- sound/pci/asihpi/hpioctl.c | 62 +++++++++----------- sound/pci/asihpi/hpios.h | 14 ++--- 7 files changed, 147 insertions(+), 170 deletions(-) (limited to 'sound/pci') diff --git a/sound/pci/asihpi/asihpi.c b/sound/pci/asihpi/asihpi.c index f56a1b8358b1..2402801388c9 100644 --- a/sound/pci/asihpi/asihpi.c +++ b/sound/pci/asihpi/asihpi.c @@ -25,6 +25,8 @@ #include "hpi_internal.h" #include "hpimsginit.h" #include "hpioctl.h" +#include "hpicmn.h" + #include #include @@ -119,12 +121,7 @@ struct clk_cache { struct snd_card_asihpi { struct snd_card *card;
