From 1df989242d3d790aec79e72d12874bf763c958e1 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 7 Feb 2017 14:38:51 +0100 Subject: [PATCH] ALSA: x86: mark hdmi suspend/resume functions as __maybe_unused The two functions are unused when CONFIG_PM_SLEEP is disabled: sound/x86/intel_hdmi_audio.c:1633:12: error: 'hdmi_lpe_audio_resume' defined but not used [-Werror=unused-function] sound/x86/intel_hdmi_audio.c:1622:12: error: 'hdmi_lpe_audio_suspend' defined but not used [-Werror=unused-function] Marking them as __maybe_unused avoids the warning without introducing an ugly #ifdef.
