This one looks more like "is this trip point valid?" than "is this trip
point enabled?", isn't it?
By having such a function to check if a trip is enabled, one would
expect to have functions to enable / disable trips points.
What do you think of naming it:
of_thermal_is_trip_valid()
?

Even your check is about looking if the trip value is within a range,
telling the caller if the trip is valid or not, right?

Missing:
EXPORT_SYMBOL_GPL(of_thermal_is_trip_en);
or

Same as in patch 01, this produces compilation error. Please, name your
parameters.
