From 997ef6b2627c54f5404c2f444e52c7140d1b6d01 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 28 Feb 2018 18:19:37 -0500 Subject: media: renesas-ceu: mark PM functions as __maybe_unused The PM runtime operations are unused when CONFIG_PM is disabled, leading to a harmless warning: drivers/media/platform/renesas-ceu.c:1003:12: error: 'ceu_runtime_suspend' defined but not used [-Werror=unused-function] static int ceu_runtime_suspend(struct device *dev) ^~~~~~~~~~~~~~~~~~~ drivers/media/platform/renesas-ceu.c:987:12: error: 'ceu_runtime_resume' defined but not used [-Werror=unused-function] static int ceu_runtime_resume(struct device *dev) ^~~~~~~~~~~~~~~~~~ This adds a __maybe_unused annotation to shut up the warning.
