The module_i2c_driver() macro can be used to reduce above code.
module_i2c_driver(foo_driver);
Note that some functions are marked by `__init'. These functions can
be removed after kernel booting (or module loading) is completed.
Likewise, functions marked by `__exit' are dropped by the compiler when
the code is built into the kernel, as they would never be called.
