Getting this errors.

Not sure what it mean, but here how this functions looks in code:

void CAN2_ORed_IRQHandler(void)
{
    FLEXCAN_IRQHandler(2U);
}

This code is from NXP SDK for S32K144 MCU.

It's interrupt handlers, so they are never called from code, Maybe it's an issue. Anyway, is it possible to ignore such functions?

This is a tricky one to come up with a good fix but I suggest to set data['calls'] = set() as a quick fix to get some result at all.
for a better fix: functions without caller may get called by a function pointer or other methods so for a worst case scenario they should be considdered called on top of the worst call.
