[PATCH 0/4] constify thermal_zone_of_device_ops structures

[Julia Lawall]

The thermal_zone_of_device_ops structures are only passed as the fourth
argument to thermal_zone_of_sensor_register, which is declared as const.
Thus the thermal_zone_of_device_ops structures themselves can be const.

Done with the help of Coccinelle.
