If anyone has any objections, please let me know. ------------------ From: Anders Roxell commit 75274b33e779ae40a750bcb4bd0b07c4dfef4746 upstream. 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 Signed-off-by: Rafael J.
