It should be left to the drivers to enable and disable the device on the MEI bus when e.g getting probed. For drivers to be able to safely call the enable and disable hooks, the mei_cl_ops must be set before it's probed and thus this should happen before registering the device on the MEI bus. Hence the mei_cl_add_device() prototype change.
