| Message-ID | <qVE6E-8tR-57@gated-at.bofh.it> |
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]
