From: Arnd Bergmann Date: Mon, 12 Sep 2016 15:32:58 +0000 (-0300) Subject: [media] atmel-isc: mark PM functions as __maybe_unused X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b7e5063589646f95520bc21d1c87c96671bd5101;p=openwrt%2Fstaging%2Fblogic.git [media] atmel-isc: mark PM functions as __maybe_unused The newly added atmel-isc driver uses SET_RUNTIME_PM_OPS() to refer to its suspend/resume functions, causing a warning when CONFIG_PM is not set: media/platform/atmel/atmel-isc.c:1477:12: error: 'isc_runtime_resume' defined but not used [-Werror=unused-function] media/platform/atmel/atmel-isc.c:1467:12: error: 'isc_runtime_suspend' defined but not used [-Werror=unused-function] This adds __maybe_unused annotations to avoid the warning without adding an error-prone #ifdef around it.
