Backport of 81ad4276b505e987dd8ebbdf63605f92cd172b52 failed to adjust
for intervening ->get_trip_temp() argument type change, thus causing
stack protector to panic.

drivers/thermal/thermal_core.c:1569:41: warning: passing argument 3 of
‘tz->ops->get_trip_temp’ from incompatible pointer type [-Wincompatible-pointer-types]
