Subject: [PATCH 5/5] OPP: No need to defer probe from _opp_attach_genpd()
Date:   Fri, 13 Oct 2023 14:18:41 +0530
Message-Id: <4cd8fe2135128168c1cd80482359dc7a46550085.1697186772.git.viresh.kumar@linaro.org>

When the new interface for attaching genpd's via the OPP core was added,
it was possible for required_opp_count to be zero, but not anymore.

Remove the unused check.
