Worse yet, I once experienced a double-definition error, that is, I had

__init int init_module(void) {
/* module1 */
}

and, in another .c file,

__init int init_module(void) {
/* module2 */
}

and making them both CONFIG_...=y gave a typical double-definition link
time error in vmlinux. The proper way (IMO) is

static __init int blah_init(void) { ... }
module_init(blah_init);

Then it does not even matter if blah_init is defined in two different
modules.
