Subject: [PATCH 11/12] cpufreq: governor: Make dbs_data_mutex static
Date: Thu, 18 Feb 2016 02:33:43 +0100	[thread overview]
Message-ID: <1655404.H6dIaK3J3n@vostro.rjw.lan> (raw)
In-Reply-To: <2938006.67J0esUvOA@vostro.rjw.lan>

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

That mutex is only used by cpufreq_governor_dbs() and it doesn't
need to be exported to modules, so make it static and drop the
export incantation.

No functional changes.
