Hi Sivaprasad,

Is this '(lcoreid_t)' cast required? Because of integer promotion I
think result will be correct without casting.

(And without integer promotion considered, casting needs to be done on
one of the variables, not to the result, because result may be already
cast down I think. Anyway this is not required for this case since
variables are u16.)
