From: Arnd Bergmann Date: Fri, 30 Sep 2016 22:36:54 +0000 (-0700) Subject: Input: ektf2127 - mark PM functions as __maybe_unused X-Git-Tag: v4.9-rc4~5^2~3^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=979987ded3a5ae1fb60ef751bdf185c502d70590;p=platform%2Fkernel%2Flinux-exynos.git Input: ektf2127 - mark PM functions as __maybe_unused The newly added ektf2127 driver uses the SIMPLE_DEV_PM_OPS macro to conditionally refer to the resume/suspend functions, which causes a warning when CONFIG_PM_SLEEP is disabled: drivers/input/touchscreen/ektf2127.c:168:12: error: 'ektf2127_resume' defined but not used [-Werror=unused-function] drivers/input/touchscreen/ektf2127.c:156:12: error: 'ektf2127_suspend' defined but not used [-Werror=unused-function] We could either put these functions inside of an #ifdef or add __maybe_unused annotations. This uses the second approach, which is generally more foolproof.
