cpuidle: coupled: remove unused define cpuidle_coupled_lock
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] Signed-off-by: Anders Roxell <anders.roxell@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
