From fe4cb86cdea781e969f37b9aa9db95577ff485f2 Mon Sep 17 00:00:00 2001 From: Jérémy Lefaure Date: Fri, 16 Dec 2016 19:25:27 -0500 Subject: ALSA: cs5535audio: fix unused warnings on resume/suspend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When CONFIG_PM_SLEEP is disabled, SIMPLE_DEV_PM_OPS does not use snd_cs5535audio_resume and snd_cs5535audio_suspend functions: sound/pci/cs5535audio/cs5535audio_pm.c:77:12: warning: ‘snd_cs5535audio_resume’ defined but not used [-Wunused-function] static int snd_cs5535audio_resume(struct device *dev) ^~~~~~~~~~~~~~~~~~~~~~ sound/pci/cs5535audio/cs5535audio_pm.c:58:12: warning: ‘snd_cs5535audio_suspend’ defined but not used [-Wunused-function] static int snd_cs5535audio_suspend(struct device *dev) ^~~~~~~~~~~~~~~~~~~~~~~ Adding __maybe_unused to the declaration of these functions removes the warnings.
