Even after following MISRA Guidelines and Model adviser ran with zero errors POLYSPACE is throwing MISRA C 2012 violations

u8_retriesCounter hints that you are working with an 8 bit unsigned value. In C when you add 1 to the maximum 8 bit unsigned value, the value overflows back to 0 rather than saturating.

I am not currently convinced that qY is anything other than 8 bit unsigned; if so then it cannot be greater than 255.

Better code would be

if SMIT_EHL_LITE_b_DW.u8_retriesCounter >= 254U
    qy = 255U;
else
    qy = SMIT_EHL_LITE_b_DW.u8_retriesCounter + 1U;
end
