    Subject[PATCH 50/76] cpuidle: remove useless array definition in cpuidle_structure
    Date
    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.
