When I was writing an i2c driver, I was taught to drop the init and
exit functions in favor of a module_i2c_driver() call. You could check
it with grep or lxr to see the details in other existing drivers. I
might be totally wrong as I have not much experience, but I thought I
would ask it either way... It does not hurt (at least not me). ;-)

Fwiw, git will not help people using lxr for instance, and I would
personally mention them in the copyrights instead. You put this file
together, so IMO you are the author even if the copyrights is held by
other people. But I do not know the kernel rules, so I might be
totally wrong, so it is not a problem for me if you do not change it.
