But the I2C device ID info is\npopulated via the first compatible string, cf. modalias population in\nof_i2c_get_board_info(). Since there is no \"ina232\" entry in the legacy\nI2C device ID table either, the struct i2c_device_id *id pointer in the\nprobe function is NULL.\n\nFix this by using the already populated type variable instead, which\npoints to the proper driver data. Since the name is also wanted, add a\ngeneric one to the ina2xx_config table."
