The latter was tied to the regulator device using the config's driver_data field, which meant that the variables could not be constant. Since each regulator device has a pointer to its regulator_desc, and mt6358_regulator_info wraps that, the driver could use container_of() to retrieve it instead. Switch to using container_of(), drop tha driver_data setting, and const-ify all the regulator descriptions.
