I've fixed most of the warnings, except the following. The first one
will require some restructuring of the variable names or the for loop
to fit into 80 chars and should probably be done in a separate patch.
The next three warnings should be left as it is since the lines are
longer by only a few characters and keeping it on a single line aids
readability, IMO.
The last warning gets fixed automatically as a result of patch 8, so I
left it there.

OK, my git hooks automatically add those when I pull those patches
back to spin a new series with reviewed-by/acked-by. I will disable
the hook.

Sending it out in a few moments as v7.

Thanks,
