   4 Subject: [PATCH] hwmon: emc2305: Add calls to initialise of cooling
   5  maps
   6
   7 Commit 46ef9d4ed26b ("hwmon: emc2305: fixups for driver submitted to
   8 mailing lists") missed adding the call to thermal_of_cooling_device_register
   9 required to configure any cooling maps for the device, hence stopping it
  10 from actually ever changing speed.
