From b07609cf88e51043d81809845384f96cffb3ab3e Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 22 Aug 2012 15:55:45 -0700 Subject: [PATCH] ARM: msm: Remove unused idle.c Forcing arm_pm_idle to be msm_idle() doesn't make sense in configurations that don't have CONFIG_MSM7X00A_IDLE=y (i.e. any targets that aren't 7x00a). Furthermore, that config doesn't even exist, so this entire file is dead code. Just remove it so we can use the default idle support on MSM.
