From 44a9ffd4eb99ada6c1496a735a414414fef30696 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 17 Aug 2018 05:53:42 -0400 Subject: [PATCH] media: camss: mark PM functions as __maybe_unused The empty suspend/resume functions cause a build warning when they are unused: drivers/media/platform/qcom/camss/camss.c:1001:12: error: 'camss_runtime_resume' defined but not used [-Werror=unused-function] drivers/media/platform/qcom/camss/camss.c:996:12: error: 'camss_runtime_suspend' defined but not used [-Werror=unused-function] Mark them as __maybe_unused so the compiler can silently drop them.
