第二个参数是要读取的数据块的起始的寄存器的地址，也就是通过I2C总线从0x00寄存器开始连续读sizeof(struct xydata_t)个数据到y_data中。

i2c: Fix the i2c_smbus_read_i2c_block_data() prototype Let the drivers specify how many bytes they want to read with i2c_smbus_read_i2c_block_data(). So far, the block count was hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense. Many driver authors complained...
