thermal/drivers/rcar_thermal: Constify static thermal_zone_device_ops

prabhakarlad · dlezcano · commit c7114365e3b7 · 2022-10-04T11:21:18.000+02:00
The only usage of rcar_thermal_zone_of_ops is to pass its address to devm_thermal_of_zone_register(), which takes a pointer to const struct thermal_zone_device_ops. Make it const to allow the compiler to put it in read-only memory.
