[RFC PATCH 01/19] cpufreq: do not expose cpufreq_governor_lock

Show all headers | View raw

From: Michael Turquette <mturquette@baylibre.com>

Since commit 3a91b069eabf ("cpufreq: governor: Quit work-handlers early if
governor is stopped") cpufreq_governor_lock is not used anywhere outside
cpufreq.c. Make it static again.
