From 043c86b6f2d54cfee8ec67e1f7f49156a68b2bd2 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Fri, 9 May 2014 06:43:26 +0900 Subject: [PATCH] ARM: EXYNOS: Use cpuidle_register Use the cpuidle generic function 'cpuidle_register'. That saves us from some extra lines of code and unneeded variables. A side effect of this change is a bug fix where before the cpuidle driver was registered for each_online_cpu and now it is for each_possible_cpu.
