Subject: [PATCH 4.18 191/350] OPP: Free OPP table properly on performance state irregularities
4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Viresh Kumar <viresh.kumar@...aro.org>
commit 2fbb8670b4ff4454f1c0de510f788d737edc4b90 upstream.
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@...r.kernel.org> # v4.18
