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 <redacted>
Could you please forward this patch upstream? The driver was introduced
in 4126c0197bc8 ("cpuidle: add support for states that affect multiple
cpus") with the cpuidle_coupled_lock variable unused. This is not -RT
specific.
