[PATCH] drivers/cpuidle: coupled: remove unused define cpuidle_coupled_lock

From: Anders Roxell
Date: Wed Jan 27 2016 - 14:33:08 EST


This was found with the -RT patch enabled, but the fix should apply to
non-RT also.

Used multi_v7_defconfig+PREEMPT_RT_FULL=y and this caused a compilation
warning without this fix:
../drivers/cpuidle/coupled.c:122:21: warning: 'cpuidle_coupled_lock'
defined but not used [-Wunused-variable]
