Issue of the Implementation # L0286

Brief

hwmon:(stts751) buffer overread on wrong chip configuration

Detailed Description

If stts751 hw by some reason reports conversion rate bigger then 9:

  ret = i2c_smbus_read_byte_data(priv->client, STTS751_REG_RATE);

then dereference stts751_intervals[priv->interval] leads to buffer overread.
