Therefore it is better to convert enum->pointer for data match and extend match support for both ID and OF tables by using i2c_get_match_data() by adding struct rt1711h_chip_info with did variable and replacing did->info in struct rt1711h_chip. Later patches will add more hw differences to struct rt1711h_chip_info and avoid checking did for HW differences.
