As Heiko already answered, you could propose a lot of this kind of
changes with just minor benefit. I do not want to push them in single
patches. Either there is a cleanup patch for explicit initialisation of
local variables in the whole qeth driver, or we take care about such
minor changes, once we touch the code anyway due to other reasons.
