The conflict is resolved correctly,  the conflicts are between Greg's misc-char 
 and driver-core git trees.
Actually I've asked Greg this git expertise question: how the **exact** 
conflict resolution is carried between git trees (before it is finally resolved 
in upstream for all.). 
For next time If anyone has the answer, please let me know.

Thanks
Tomas
