Subject: [PATCH] soc: qcom: rpmh: Update rpmh_invalidate function to return void
Date:   Thu, 18 Jun 2020 18:35:53 +0530
Message-Id: <1592485553-29163-1-git-send-email-mkshah@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently rpmh_invalidate() always returns success. Update its
return type to void.
