Subject: [PATCH V2 01/12] OPP: Free OPP table properly on performance state irregularities
Date: Wed, 19 Sep 2018 15:20:20 -0700	[thread overview]
Message-ID: <2fbb8670b4ff4454f1c0de510f788d737edc4b90.1537394233.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1537394233.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1537394233.git.viresh.kumar@linaro.org>

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.

Cc: 4.18 <stable@vger.kernel.org> # v4.18
Fixes: 3ba98324e81a ("PM / OPP: Get performance state using genpd helper")
