Right, but this doesn't solve my problem.  What I was trying to say
was that we should get the default governor if tz->tzp->governor_name
is not initialized.  of_parse_thermal_zones() calls
thermal_zone_device_register() with a tzp that has an empty
governor_name and ends up with no governor.

I'll send a patch that gets you the default governor if you don't
specify a governor_name in tzp and add your patch on top.
