Function thermal_zone_device_register, in the for circle, if the
first if branch set the count bit in tz->trips_disabled, there is
no need to set in the other if branch again.
This change is to make the code run a bit fast and readable.

What about ?
if (tz->ops->get_trip_type(tz, count, &trip_type) ||
tz->ops->get_trip_temp(tz, count, &trip_temp) ||
!trip_temp)
set_bit(count, &tz->trips_disabled);

Please, take the opportunity to fix the author name to be the same as
the signed-off-by.
