imx_mu_suspend_noirq()/imx_mu_resume_noirq() are currently used only when CONFIG_PM_SLEEP configuration options is enabled. Having it disabled triggers the following warning at compile time:
drivers/mailbox/imx-mailbox.c:611:12: warning: ‘imx_mu_resume_noirq’ defined but not used [-Wunused-function] static int imx_mu_resume_noirq(struct device *dev) drivers/mailbox/imx-mailbox.c:601:12: warning: ‘imx_mu_suspend_noirq’ defined but not used [-Wunused-function] static int imx_mu_suspend_noirq(struct device *dev) Make imx_mu_suspend_noirq()/imx_mu_resume_noirq() __maybe_unused to address the issue.
