The sparse tool complains as follows:
kernel/sched/topology.c:211:1: warning:
symbol 'sched_energy_mutex' was not declared. Should it be static?
kernel/sched/topology.c:212:6: warning:
symbol 'sched_energy_update' was not declared. Should it be static?
This symbol is not used outside of topology.c, so this
commit marks it static.

FWIW, that has been reported some time ago:
https://lore.kernel.org/lkml/1606218731-3999-1-git-send-email-zou_wei@huawei.com/
https://lore.kernel.org/lkml/1606271447-74720-1-git-send-email-zou_wei@huawei.com/
But otherwise, this looks OK to me.
Thanks,
Quentin
