From: Arnd Bergmann Date: Wed, 2 Mar 2016 15:59:06 +0000 (+0100) Subject: ASoC: rockchip: use __maybe_unused to hide st_irq_syscfg_resume X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8fc2198aab117a4bc16ee305caef19c4c7e7f5c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ASoC: rockchip: use __maybe_unused to hide st_irq_syscfg_resume The rockchip spdif driver uses SIMPLE_DEV_PM_OPS to conditionally set its power management functions, but we get a warning about rk_spdif_runtime_resume being unused when CONFIG_PM is not set: sound/soc/rockchip/rockchip_spdif.c:67:12: error: 'rk_spdif_runtime_resume' defined but not used [-Werror=unused-function] This adds a __maybe_unused annotation so the compiler knows it can silently drop it instead of warning.
