Thats good to know thanks for pointing that out, I have picked up a few
discrepancies with interpretation and checkpatch.pl.
Am noting it and trying to patch checkpatch.pl as I continue :).
I think checkpatch.pl points this out as the opposite to interpretation
thou otherwise I would not have patched it I guess.
Current TODO on checkpatch:
1. type i = 0 ; /* space before ; is not picked up by checkpatch.
2. What you mentioned is interpreted different by checkpatch.pl

Joe
