You need to declare the parameter name with a name     ---------------^ .

This produces a compilation error if CONFIG_THERMAL_OF is not set:
In file included from drivers/thermal/step_wise.c:28:0:
drivers/thermal/thermal_core.h: In function ‘of_thermal_get_ntrips’:
drivers/thermal/thermal_core.h:96:48: error: parameter name omitted
