Welcome to the wonderful world of magic initialisation.

(1) Declare your initialisation function as int __init foo_init(void).

(2) Decide when your function needs to be called, e.g. after initialisers
    for A, B, C but before initialisers for X, Y, Z.

(3) Edit the Makefile to insert obj-$(CONFIG_FOO) after the objects
    that contain initialisers A, B, C and before the objects for
    initialisers X, Y, Z.

(4) Document why the order of this routine is required!  Without docs
    in the Makefile we have no idea if object order is correct or not.
