From: Arnd Bergmann Date: Wed, 2 Mar 2016 17:11:46 +0000 (-0800) Subject: Input: snvs_pwrkey - use __maybe_unused to hide pm functions X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2d1a792357bf5ef7022f3ba82ab8976609425f4b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
