Subject: [PATCH 26/31] OPP: Remove dev_pm_opp_set_supported_hw() and friends
Date: Thu, 26 May 2022 17:12:25 +0530 [thread overview]
Message-ID: <c8dc74650009e96ef5f8741b77e3e49e50ba458c.1653564321.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1653564321.git.viresh.kumar@linaro.org>
Now that everyone has migrated to dev_pm_opp_set_config(), remove the
public interface for dev_pm_opp_set_supported_hw() and friends.
