Your driver does not use it. Drop all such things which are not used by drivers or explain why they are needed to be in the binding - what do they bind. I asked for this already, for exactly the same thing. I did not check the rest, so next time I will choose any other random define and if I do not find it explained nor used, I will question it. Because you tend to apply pieces of review instead of really change your code. > ``` Best regards, Krzysztof
