From 5d05e81516cfe7606ee0cd8278fe225314dccfbe Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 19 Apr 2017 19:52:43 +0200 Subject: rtc: sh: mark PM functions as unused The sh_rtc_set_irq_wake() function is only called from the suspend/resume handlers that may be hidden, causing a harmless warning: drivers/rtc/rtc-sh.c:724:13: error: 'sh_rtc_set_irq_wake' defined but not used [-Werror=unused-function] static void sh_rtc_set_irq_wake(struct device *dev, int enabled) The most reliable way to avoid the warning is to remove the existing #ifdef and mark the two functions as __maybe_unused so the compiler can silently drop all three when there is no reference.
