[PATCH 06/10] usbtmc: indent & braces disagree, something else isdesired

[Ilpo Järvinen]

It seems that there's rather involved way to say something
which is commonly written in a plain simple form.

Some type changes would probably be necessary to get gcc
to do bitops instead of divide but it's no worse after my
change than before I think.
