File 0308-drm-hisilicon-hibmc-mark-PM-functions-__maybe_unused.patch of Package drm.7971
From a046d112109b8412aba524e8154ac6b3517498b2 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd@arndb.de> Date: Thu, 24 Nov 2016 17:30:26 +0100 Subject: [PATCH 8/8] drm/hisilicon/hibmc: mark PM functions __maybe_unused MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Git-commit: b61abd49c5dd07d3b97b638128982c3feef99a93 Patch-mainline: v4.10-rc1 References: fate#322061 When CONFIG_PM_SLEEP is disabled, we get a harmless warning drm/hisilicon/hibmc/hibmc_drm_drv.c:115:12: error: ‘hibmc_pm_resume’ defined but not used [-Werror=unused-function] drm/hisilicon/hibmc/hibmc_drm_drv.c:97:12: error: ‘hibmc_pm_suspend’ defined but not used [-Werror=unused-function] Marking the functions as __maybe_unused avoids the warning without having to add an #ifdef.
