From db70b04407a63668e5fee773f76f90367492fd25 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Mon, 26 Mar 2012 14:51:27 +0200 Subject: [PATCH] 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.
