高版本linux3.3内核中没用i2c_attach_client

现在的看的linux3.3内核i2c 的总线驱动中i2c_adapter结构为:

struct i2c_adapter {
	struct module *owner;
	unsigned int class;		  /* classes to allow probing for */
	const struct i2c_algorithm *algo; /* the algorithm to access the bus */
	void *algo_data;

	/* data fields that are valid for all devices	*/
	struct rt_mutex bus_lock;

	int timeout;			/* in jiffies */
	int retries;
	struct device dev;		/* the adapter device */

	int nr;
	char name[48];
	struct completion dev_released;

	struct mutex userspace_clients_lock;
	struct list_head userspace_clients;
};

这个表中的内容和LDD3等中的结构体区别在于没用成员变量struct list_head client。所以就不需要进行i2c_attach_client来实现。
