  31 Reading thermal sensor on mt7986 devices returns invalid temperature:
  32
  33 bpi-r3 ~ # cat /sys/class/thermal/thermal_zone0/temp
  34  -274000
  35
  36 Fix this by adding missing members in mtk_thermal_data struct which were
  37 used in mtk_thermal_turn_on_buffer after commit 33140e668b10.
