When CONFIG_PM_SLEEP is not set, there is a warning that qcom_ipcc_pm_resume() is unused: drivers/mailbox/qcom-ipcc.c:258:12: error: 'qcom_ipcc_pm_resume' defined but not used [-Werror=unused-function] 258 | static int qcom_ipcc_pm_resume(struct device *dev) | ^~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old ones") reworked the PM_OPS macros to avoid this problem. Use NOIRQ_SYSTEM_SLEEP_PM_OPS directly so that qcom_ipcc_pm_resume() always appears to be used to the compiler, even though it will be dead code eliminated in the !CONFIG_PM_SLEEP case.
