SND_AC97_BUS(9) Control/Mixer API SND_AC97_BUS(9)NAME
snd_ac97_bus - create an AC97 bus component
int snd_ac97_bus(struct snd_card * card, int num, struct snd_ac97_bus_ops * ops, void * private_data, struct snd_ac97_bus ** rbus);
the card instance
the bus number
the bus callbacks table
private data pointer for the new instance
the pointer to store the new AC97 bus instance.
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.
Zero if successful, or a negative error code on failure.

i2c_add_numbered_adapter - declare i2c adapter, use static bus number
int i2c_add_numbered_adapter(struct i2c_adapter * adap);
the adapter to register (with adap->nr initialized)
This routine is used to declare an I2C adapter when its bus number matters. For example, use it for I2C adapters from system-on-chip CPUs,
or otherwise built in to the system's mainboard, and where i2c_board_info is used to properly configure I2C devices.
If the requested bus number is set to -1, then this function will behave identically to i2c_add_adapter, and will dynamically assign a bus
If no devices have pre-been declared for this bus, then be sure to register the adapter before any dynamically allocated ones. Otherwise
the required bus ID may not be available.
When this returns zero, the specified adapter became available for clients using the bus number provided in adap->nr. Also, the table of
I2C devices pre-declared using i2c_register_board_info is scanned, and the appropriate driver model device nodes are created. Otherwise, a
negative errno value is returned.
