In dbsc5_read_vref_training the arrays dvw_min_byte0_table and dvw_min_byte1_table have 128 elements per channel. The variable vref_stop_index is limited to be a maximum of 128. This means that the index used to access the arrays must use a test of '< vref_stop_index' rather than '<= vref_stop_index' in order to prevent out of bounds accesses to the arrays. This issue was found by Smatch.
