Subject: cpuidle: remove useless array definition in cpuidle_structure
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=db70b04407a63668e5fee773f76f90367492fd25;p=openwrt%2Fstaging%2Fblogic.git

cpuidle: remove useless array definition in cpuidle_structure

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.
