NAME
       snd_ac97_bus - create an AC97 bus component

SYNOPSIS
       int snd_ac97_bus(struct snd_card * card, int num, struct snd_ac97_bus_ops * ops, void * private_data, struct snd_ac97_bus ** rbus);

ARGUMENTS
       card
	   the card instance

       num
	   the bus number

       ops
	   the bus callbacks table

       private_data
	   private data pointer for the new instance

       rbus
	   the pointer to store the new AC97 bus instance.

DESCRIPTION
       Creates an AC97 bus component. An struct snd_ac97_bus instance is newly allocated and initialized.

       The ops table must include valid callbacks (at least read and write). The other callbacks, wait and reset, are not mandatory.

       The clock is set to 48000. If another clock is needed, set (*rbus)->clock manually.

       The AC97 bus instance is registered as a low-level device, so you don't have to release it manually.

RETURN
       Zero if successful, or a negative error code on failure.
