Wysocki The only actually used thermal netlink notification routine related to cooling devices is thermal_notify_cdev_state_update(). The other two, thermal_notify_cdev_add() and thermal_notify_cdev_delete(), are never used. So as to get rid of dead code, drop thermal_notify_cdev_add/delete(), which can be added back if they turn out to be ever needed, along with the related code. In analogy with the previous thermal netlink API changes, redefine thermal_notify_cdev_state_update() to take a const cdev pointer as its first argument and let it extract the requisite information from there by itself. No intentional functional impact. Signed-off-by: Rafael J.
