There is a potential buffer overflow issue in bmi323

[Qianqiang Liu]

Hi,

I reviewed the following code in drivers/iio/imu/bmi323/bmi323_core.c:

2245         for (unsigned int i = 0; i < ARRAY_SIZE(bmi323_ext_reg_savestate); i++) { <-
2246                 ret = bmi323_write_ext_reg(data, bmi323_reg_savestate[i], <-
2247						savestate->reg_settings[i]);
2248                 if (ret) {
2249                         dev_err(data->dev,
2250                                 "Error writing bmi323 external reg 0x%x: %d\n",
2251                                 bmi323_reg_savestate[i], ret);
2252                         return ret;
2253                 }
2254         }

The array size of the "bmi323_ext_reg_savestate" is twelve, and the
array size of "bmi323_reg_savestate" is nine.

Is it possible that "bmi323_reg_savestate" may have buffer overflow
issue?
