From 013e2b722aa9b18649dbae8422ced270c793f9d4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 15 Dec 2017 13:51:52 +0100 Subject: [PATCH] drm/tegra: Mark Tegra186 display hub PM functions __maybe_unused The newly introduced driver has optional suspend/resume functions, causing a warning when CONFIG_PM is disabled: drivers/gpu/drm/tegra/hub.c:749:12: error: 'tegra_display_hub_resume' defined but not used [-Werror=unused-function] drivers/gpu/drm/tegra/hub.c:733:12: error: 'tegra_display_hub_suspend' defined but not used [-Werror=unused-function] This marks them __maybe_unused to shut up the warnings.
