Instead of requiring the caller of thermal_notify_tz_trip_change() to
provide specific values needed to populate struct param in it, make it
extract those values from objects passed to it by the caller via const
pointers.

No intentional functional impact.

I was wondering if it's not too long line, but I can see it's common
in that header file. Shouldn't we break such lines like:

static inline
int thermal_notify_tz_trip_change(const struct thermal_zone_device *tz,
				const struct thermal_trip *trip)

?
Although, it would apply to all other long lines in that header, so not
particularly to this $subject.

Other than the comment above, LGTM.

IMO the additional line break doesn't really make it easier to read.

And note that it is OK now to have code lines longer than 80 chars (as
long as they are not longer than 100 chars IIRC), although it is still
recommended (but not required any more) to observe the "old" 80 chars
length limit.

Well, right.
