Subject: [PATCH] hwmon: emc2305: Add calls to initialise of cooling
|
||
|
|
maps
|
||
|
|
|
||
|
|
Commit 46ef9d4ed26b ("hwmon: emc2305: fixups for driver submitted to
|
||
|
|
mailing lists") missed adding the call to thermal_of_cooling_device_register
|
||
|
|
required to configure any cooling maps for the device, hence stopping it
|
||
|
|
from actually ever changing speed.
