Subject: [PATCH] drivers: thermal: processor_thermal_device: Fix build warning
As a system sleep callback, proc_thermal_resume() should be defined only
if CONFIG_PM_SLEEP is defined.
This fixes a build warning when CONFIG_PM_SLEEP is not set,
drivers/thermal/intel/int340x_thermal/processor_thermal_device.c:446:12: error: 'proc_thermal_resume' defined but not used [-Werror=unused-function]
static int proc_thermal_resume(struct device *dev)
Fixes: aaba9791fbb4 ("drivers: thermal: processor_thermal: Read PPCC on resume")
