De struct:

static struct i2c_adapter i2c_ipmi_adapter = {
       .owner          = THIS_MODULE,
       .name           = "IPMI adapter",
       .id             = I2C_ALGO_IPMI | I2C_HW_IPMI,
       .algo           = &i2c_ipmi_algorithm,
};

met

       list_for_each(item, &i2c_ipmi_adapter.clients) {
       client = list_entry(item, struct i2c_client, list);
       if(id == client->id)
               return client;


dat gaat dus goed

maar:
static struct i2c_adapter i2c_ipmi_adapter = {
        .owner          = THIS_MODULE,
        .name           = "IPMI adapter",
        .id             = I2C_ALGO_IPMI | I2C_HW_IPMI,
        .algo           = &i2c_ipmi_algorithm,
};

met

81        for (i = 0; i < I2C_CLIENT_MAX; i++)
82                if (client == i2c_ipmi_adapter.clients[i])
83                        return i;

geeft:
