Subject: [PATCH v5 08/12] cpufreq: Add stub for cpufreq_update_policy()
Date:   Tue,  3 Jul 2018 16:47:01 -0700
Message-Id: <20180703234705.227473-9-mka@chromium.org>
In-Reply-To: <20180703234705.227473-1-mka@chromium.org>
References: <20180703234705.227473-1-mka@chromium.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

cpufreq stubs out some functions when CONFIG_CPU_FREQ=n , but
cpufreq_update_policy() is not among them. The throttler driver
(https://patchwork.kernel.org/patch/10453351/) uses cpufreq as one
possible throttling mechanism, but it can still be useful without
cpufreq. Stubbing out cpufreq_update_policy() allows the throttler
driver to be built without ugly #ifdef'ery when cpufreq is disabled.
