The PM functions are never referenced when CONFIG_PM_SLEEP is disabled:
sound/soc/codecs/max98388.c:854:12: error: unused function 'max98388_suspend' [-Werror,-Wunused-function] static int max98388_suspend(struct device *dev) ^ sound/soc/codecs/max98388.c:864:12: error: unused function 'max98388_resume' [-Werror,-Wunused-function] static int max98388_resume(struct device *dev)
Fix this by using the modern SYSTEM_SLEEP_PM_OPS() macro in place of the deprecated SET_SYSTEM_SLEEP_PM_OPS() version, and use pm_sleep_ptr() to hide the entire structure as well.
On a related note, the of_match_ptr() and ACPI_PTR() macros have the same problem and would cause the device id table to be unused when the driver is built-in and the respective subsystems are disabled. This does not cause warnings unless -Wunused-const-variable is passed to the compiler, but it's better to just not use the macros at all here.
