Independent of the validity of this patch, you should not be
submitting patches that have a mix of whitespace changes and actual
changes. In the above case (the if type & DTV7 part), it looks like
these shouldn't have been included at all since it makes no functional
change.
It sounds like a nit-pick, but the reality is that its inclusion had
me staring at it for 30 seconds trying to figure out whether there was
an *actual* difference there or if it was purely whitespace.

Likewise, you should not be including unrelated changes in patches -
the above "#if 0" section not only is never compiled in to the code
(presumably it is debug code), but it has nothing to do with the fix
this patch is claiming to address.
