[PATCH 4.19 196/361] OPP: Free OPP table properly on performance state irregularities

From: Greg Kroah-Hartman
Date: Sun Nov 11 2018 - 17:28:03 EST


4.19-stable review patch. If anyone has any objections, please let me know.

------------------

From: Viresh Kumar <viresh.kumar@xxxxxxxxxx>

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.
