[PATCH 5.3 194/197] opp: of: drop incorrect lockdep_assert_held()

From: Greg Kroah-Hartman
Date: Sun Oct 27 2019 - 17:26:02 EST


From: Viresh Kumar <viresh.kumar@xxxxxxxxxx>

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.

Fixes: 5d6d106fa455 ("OPP: Populate required opp tables from "required-opps" property")
