Reading thermal sensor on mt7986 devices returns invalid temperature:
|
|
|
|
|
|
|
|
|
|
bpi-r3 ~ # cat /sys/class/thermal/thermal_zone0/temp
|
|
|
|

|
|

|
|
|
Fix this by adding missing members in mtk_thermal_data struct which were
|
|
|
|
|
used in mtk_thermal_turn_on_buffer after commit 33140e668b10.
