[PATCH 08/11] OPP: Don't remove dynamic OPPs from _dev_pm_opp_remove_table()
From: Viresh Kumar
Date: Wed Sep 12 2018 - 04:30:16 EST
Only one platform was depending on this feature and it is already
updated now. Stop removing dynamic OPPs from _dev_pm_opp_remove_table().
This simplifies lot of paths and removes unnecessary parameters.
