Subject: [PATCH 18/76] thermal: of: always set sensor related callbacks
|
|
|
|
Now that the thermal core treats -ENOSYS like the callbacks were
|
|
not present at all we no longer have to overwrite the ops during
|
|
runtime but instead can always set them and return -ENOSYS if no
|
|
sensor is registered.
