As the Dan report the smatch check the thermal driver warning: drivers/thermal/rockchip_thermal.c:551 rockchip_configure_from_dt() warn: impossible condition '(thermal->tshut_temp > ((~0 >> 1))) => (s32min-s32max > s32max)' Since the Temperature is currently represented as int not long in the thermal driver.
