From: Daniel Lezcano <daniel.lezcano@xxxxxxxxxx>
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.
