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?
