because the forte driver does this:
[tdavis@lanshark sound]$ grep ac97 forte.c
#include <linux/ac97_codec.h>
spinlock_t ac97_lock;
struct ac97_codec *ac97;
* forte_ac97_wait:
forte_ac97_wait (struct forte_chip *chip)
* forte_ac97_read:
forte_ac97_read (struct ac97_codec *codec, u8 reg)
spin_lock (&chip->ac97_lock);
if (forte_ac97_wait (chip)) {
printk (KERN_ERR PFX "ac97_read: Serial bus busy\n");
if (forte_ac97_wait (chip)) {
printk (KERN_ERR PFX "ac97_read: Bus busy reading reg
0x%x\n",
printk (KERN_ERR PFX "ac97_read: Invalid data port");
spin_unlock (&chip->ac97_lock);
* forte_ac97_write:
forte_ac97_write (struct ac97_codec *codec, u8 reg, u16 val)
spin_lock (&chip->ac97_lock);
if (forte_ac97_wait (chip)) {
printk (KERN_ERR PFX "ac97_write: Serial bus busy\n");
if (forte_ac97_wait (chip)) {
printk (KERN_ERR PFX "ac97_write: Bus busy after write\n");
spin_unlock (&chip->ac97_lock);
file->private_data = chip->ac97;
struct ac97_codec *codec = (struct ac97_codec *)
file->private_data;
if (!create_proc_read_entry("driver/forte/ac97", 0, 0,
ac97_read_proc, forte->ac97)) {
remove_proc_entry ("driver/forte/ac97", NULL);
struct ac97_codec *codec;
if ((codec = kmalloc (sizeof (struct ac97_codec), GFP_KERNEL))
== NULL)
memset (codec, 0, sizeof (struct ac97_codec));
codec->codec_read = forte_ac97_read;
codec->codec_write = forte_ac97_write;
if (ac97_probe_codec (codec) == 0) {
chip->ac97 = codec;
spin_lock_init (&chip->ac97_lock);
unregister_sound_mixer (chip->ac97->dev_mixer);
ie, it has a ac97 support in the driver, it calls ac97_probe_codec?
Is that enough or not?
