Wysocki After commit 2e38a2a981b2 ("thermal/core: Add a generic thermal_zone_set_trip() function") updating a trip point temperature doesn't actually work, because the value supplied by user space is subsequently overwritten with the current trip point hysteresis value. Fix this by parsing the number string supplied by user space after retrieving the current trip point data from the thermal zone. Also drop a redundant tab character from the code in question.
