From 2cf2a1acc6ebdffc6363de9156db8737f33c1803 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Tue, 15 Aug 2023 15:16:41 -0700 Subject: rtc: stm32: Use NOIRQ_SYSTEM_SLEEP_PM_OPS() After the switch to SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() and a subsequent fix, stm32_rtc_{suspend,resume}() are unused when CONFIG_PM_SLEEP is not set because SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() is a no-op in that configuration: drivers/rtc/rtc-stm32.c:904:12: error: 'stm32_rtc_resume' defined but not used [-Werror=unused-function] 904 | static int stm32_rtc_resume(struct device *dev) | ^~~~~~~~~~~~~~~~ drivers/rtc/rtc-stm32.c:894:12: error: 'stm32_rtc_suspend' defined but not used [-Werror=unused-function] 894 | static int stm32_rtc_suspend(struct device *dev) | ^~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors The non-"SET_" version of this macro, NOIRQ_SYSTEM_SLEEP_PM_OPS(), is designed to handle this situation by only assigning the callbacks when CONFIG_PM_SLEEP is set while allowing the functions to appear used to the compiler. Switch to that macro to resolve the warnings. There is no functional change with this, as SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() is defined using NOIRQ_SYSTEM_SLEEP_PM_OPS() when CONFIG_PM_SLEEP is set.
