From: Thomas Gleixner Date: Wed, 21 Dec 2016 19:19:54 +0000 (+0100) Subject: cpu/hotplug: Cleanup state names X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=73c1b41e63f0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git cpu/hotplug: Cleanup state names When the state names got added a script was used to add the extra argument to the calls. The script basically converted the state constant to a string, but the cleanup to convert these strings into meaningful ones did not happen. Replace all the useless strings with 'subsys/xxx/yyy:state' strings which are used in all the other places already.
