Today I trace the code. The power manager will call i2c_device_suspend function
in i2c-core.c, when neo1973 enters suspend mode. I compare the kernel between
2.6.21.6 and 2.6.17.14. There are two different methods to call device's suspend
function.

Now PM can't find the driver's suspend function. the code is as follows

driver = to_i2c_driver(dev->driver);
if (!driver->suspend)
return 0;

So I will check this part why it always can't find the suspend function
