From: Arnd Bergmann <arnd@xxxxxxxx> Without CONFIG_PM, the driver warns about unused functions: drivers/remoteproc/imx_dsp_rproc.c:1210:12: error: 'imx_dsp_runtime_suspend' defined but not used [-Werror=unused-function] 1210 | static int imx_dsp_runtime_suspend(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~~~ drivers/remoteproc/imx_dsp_rproc.c:1178:12: error: 'imx_dsp_runtime_resume' defined but not used [-Werror=unused-function] 1178 | static int imx_dsp_runtime_resume(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~~ Change the old SET_SYSTEM_SLEEP_PM_OPS()/SET_RUNTIME_PM_OPS() helpers to their modern replacements that avoid the warning, and remove the now unnecessary __maybe_unused annotations on the other PM helper functions.
