From: Daniel Lezcano <daniel.lezcano@linaro.org>
All the modules name are ro-data, it is never copied to the array.
eg.
static struct cpuidle_driver intel_idle_driver = { .name = "intel_idle", .owner = THIS_MODULE, };
It safe to assign the pointer of this ro-data to a const char *. By this way we save 12 bytes.
