You won't call anything, kernel does. You only register driver.
struct pcitbl {venids, devids}

struct driver ... = {probe=a, remove=b, tbl=pcitbl};
a() { if device from pcitbl is in the system (or has been added before
some little time) this function is called}
b() {if the device was removed from system: modules and hotplug: never
called; modules: so if modules unload; if both: if the device was
removed on the fly, or module unload}

module_init() { register_driver(driver)}
module_exit() { unregister_driver(driver); }
