From d1f08d82176246c6d8a2f1dc26be3638ed4a6083 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 3 Aug 2017 13:50:47 +0200 Subject: [PATCH] drm/msm/mdp5: mark runtime_pm functions as __maybe_unused When CONFIG_PM is disabled, we get harmless warnings about unused functions: drivers/gpu/drm/msm/mdp/mdp5/mdp5_kms.c:1025:12: error: 'mdp5_runtime_resume' defined but not used [-Werror=unused-function] static int mdp5_runtime_resume(struct device *dev) ^~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/msm/mdp/mdp5/mdp5_kms.c:1015:12: error: 'mdp5_runtime_suspend' defined but not used [-Werror=unused-function] static int mdp5_runtime_suspend(struct device *dev) ^~~~~~~~~~~~~~~~~~~~ This marks both functions as __maybe_unused so the compiler can drop them silently.
