From: Arnd Bergmann Date: Mon, 20 Aug 2018 09:35:37 +0000 (+0200) Subject: slimbus: ngd: mark PM functions as __maybe_unused X-Git-Tag: v5.4-rc1~2359^2~191 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2e6ae11dd0d1c37f44cec51a58fb2092e55ed0f5;p=platform%2Fkernel%2Flinux-rpi.git slimbus: ngd: mark PM functions as __maybe_unused qcom_slim_ngd_runtime_suspend is protected by an #ifdef, qcom_slim_ngd_runtime_idle is now, which causes a build time warning: drivers/slimbus/qcom-ngd-ctrl.c:1470:12: error: 'qcom_slim_ngd_runtime_idle' defined but not used [-Werror=unused-function] Marking both as __maybe_unused lets us get rid of the warning as well as the #ifdef.
