OK,

The previous email analysis the non-DT cases exhaustively, this email intend to
demonstrate the more frequently use case.

That is, in the *DT('OF')* based systems,
device_get_match_data() is completely equivalent to 
of_device_get_match_data().
So the net results of applying this patch are "no gains and no lost".

Things will become clear if we divide the whole problem into two cases(DT and non-DT)
to discuss, that's it. That's all I can tell.

Sorry about my broken written and sorry for the noise. Thanks for your education in
the past.
