From: Viresh Kumar <viresh.kumar@linaro.org>
commit f2edbb6699b0bc6e4f789846b99007200546c6c2 upstream.
_find_opp_of_np() doesn't traverse the list of OPP tables but instead just the entries within an OPP table and so only requires to lock the OPP table itself.
The lockdep_assert_held() was added there by mistake and isn't really required.
