Subject: [PATCH -next] sched/topology: Mark some symbols with static keyword
Date: Tue, 24 Nov 2020 19:52:11 +0800	[thread overview]
Message-ID: <1606218731-3999-1-git-send-email-zou_wei@huawei.com> (raw)

Fix the following sparse warnings:

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?
