Done. Btw, I saw another that looks legit.
drivers/hwmon/nct6775.c:1687 nct6775_update_device()
error: buffer overflow 'data->FAN_PULSE_SHIFT' 6 <= 6
drivers/hwmon/nct6775.c
1667 data->in[i][2] = nct6775_read_value(data,
1668 data->REG_IN_MINMAX[1][i]);
1669 }
1670
1671 /* Measured fan speeds and limits */
1672 for (i = 0; i < ARRAY_SIZE(data->rpm); i++) {
^^^^^^^^^^^^^^^^^^^^^^^^
This is a 7 element array.
1673 u16 reg;
1674
1675 if (!(data->has_fan & BIT(i)))
^^^^^^^^^^^^^^^^^^^^^^
I probably wouldn't have reported this originally because Smatch is bad
at these checks. (I just haven't gotten around to it yet). But we do
have fan7pin so it looks like BIT(6) can be set.
1676 continue;
1677
1678 reg = nct6775_read_value(data,
data->REG_FAN[i]);
1679 data->rpm[i] = data->fan_from_reg(reg,
1680
data->fan_div[i]);
1681
1682 if (data->has_fan_min & BIT(i))
1683 data->fan_min[i] =
nct6775_read_value(data,
1684 data->REG_FAN_MIN[i]);
1685 data->fan_pulses[i] =
1686 (nct6775_read_value(data,
data->REG_FAN_PULSES[i])
1687 >> data->FAN_PULSE_SHIFT[i]) & 0x03;
^^^^^^^^^^^^^^^^^^^^^^^^
FAN_PULSE_SHIFT is either 5 or 6 elements.
1688
1689 nct6775_select_fan_div(dev, data, i, reg);

1692 nct6775_update_pwm(dev);
