From 2d1a792357bf5ef7022f3ba82ab8976609425f4b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 2 Mar 2016 09:11:46 -0800 Subject: [PATCH] Input: snvs_pwrkey - use __maybe_unused to hide pm functions The SNVS power key driver has suspend/resume functions that are accessed using SIMPLE_DEV_PM_OPS, which hide the reference when CONFIG_PM_SLEEP is not set, resulting in a warning about unused functions: drivers/input/keyboard/snvs_pwrkey.c:183:12: error: 'imx_snvs_pwrkey_suspend' defined but not used [-Werror=unused-function] drivers/input/keyboard/snvs_pwrkey.c:194:12: error: 'imx_snvs_pwrkey_resume' defined but not used [-Werror=unused-function] This adds __maybe_unused annotations to let the compiler know it can silently drop the function definition.
