From: Geert Uytterhoeven Date: Wed, 30 May 2018 15:15:26 +0000 (+0200) Subject: ARM: shmobile: apmu: Move cpu_leave_lowpower() to SUSPEND section X-Git-Tag: v5.15~8137^2~5^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fa6e9cb2aca1cdca1b85e5b19f9cda8aac78752b;p=platform%2Fkernel%2Flinux-starfive.git ARM: shmobile: apmu: Move cpu_leave_lowpower() to SUSPEND section cpu_leave_lowpower() is used for suspend only, not for CPU hotplug. Hence move it from the HOTPLUG_CPU || SUSPEND section to the SUSPEND section.
