When CONFIG_PM_SLEEP=n, the following compilation warnings appear:
drivers/thermal/ti-soc-thermal/ti-bandgap.c:1478:12: warning:
‘ti_bandgap_suspend’ defined but not used [-Wunused-function]
static int ti_bandgap_suspend(struct device *dev)
^
drivers/thermal/ti-soc-thermal/ti-bandgap.c:1492:12: warning:
‘ti_bandgap_resume’ defined but not used [-Wunused-function]
static int ti_bandgap_resume(struct device *dev)
A few years ago, suspend/resume-related code was protected by CONFIG_PM.
But that was changed and now it's protected by CONFIG_PM_SLEEP. Fix the
warnings by converting the preprocessor test in the TI bandgap thermal
sensor driver from testing CONFIG_PM to testing CONFIG_PM_SLEEP.
