From 08c373e5123b4595588ae1a7aa7e00a046c61cc6 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 21 Apr 2014 01:26:58 +0200 Subject: sched/idle: Make cpuidle_idle_call() void The only value ever returned by cpuidle_idle_call() is 0 and its only caller ignores that value anyway, so make it void.
