Please use the imperative, in the subject line and in the patch. Also,
try to say something other than "fixes" about what you do, which is not
very descriptive. Say what you actually did and why, eg remove unneeded
parentheses around the arguments of || to reduce clutter.

It is useful to mention that the change was suggested by checkpatch. It
is not essential to copy the whole checkpatch message, or at least not all
of them.

thanks,
julia
