Subject: [PATCH 01/11] OPP: Free OPP table properly on performance state irregularities
Date:   Wed, 12 Sep 2018 13:58:40 +0530
Message-Id: <14486fb4c32047983ace6af4f4ffe2366242f3b5.1536736872.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1536736872.git.viresh.kumar@linaro.org>
References: <cover.1536736872.git.viresh.kumar@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The OPP table was freed, but not the individual OPPs which is done from
_dev_pm_opp_remove_table(). Fix it by calling _dev_pm_opp_remove_table()
as well.
