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.
