| Subject: [PATCH 125/286] 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. |
| |
| Fixes: dab5aec64bf5 ("rtc: sh: add support for rza series") |
