Fw: TPS65910 Regulator Isuue

[Amit Mahadik]

Hi,     I am working on integrating TPS695190 regulator code into kernel version 4.4.16. The regulator powers MMC card slot using Designware MMC controller. I have declared the necessary code in my board.c file. The MMC card slot is powered by ldo8 supply declared as
-----------------------------------------------------------------------------Code---------------------------------------------------------------------------------

static struct regulator_consumer_supply opv5xc_ldo8_supply[] = {
        REGULATOR_SUPPLY("sd_vdd", NULL),
};

static struct regulator_init_data opv5xc_ldo8 = {
        .constraints = {
                .min_uV = 1000000,
                .max_uV = 3300000,
                .valid_ops_mask = (REGULATOR_CHANGE_VOLTAGE |
                                REGULATOR_CHANGE_STATUS),
                .boot_on = 1,
        },
        .num_consumer_supplies = ARRAY_SIZE(opv5xc_ldo8_supply),
        .consumer_supplies = opv5xc_ldo8_supply,
};
static struct tps65910_board tps65910_pdata = {
              .tps65910_pmic_init_data[TPS65911_REG_LDO8]     = &opv5xc_ldo8,
};
static struct i2c_board_info __initdata opv5xc_i2c1_devs[] = {
        {
                I2C_BOARD_INFO ("tps65911", TPS65910_I2C_ID1),
                .platform_data = &tps65910_pdata,
        },
};
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
When I call regulator_get struct regulator *sd_vdd = regulator_get(NULL, "sd_vdd");  function from the Designware MMC driver code function the kernel panics.I have attached the log file for reference. Can somebody please let me know what I am doing wrong here?
Regards,Amit.
