[Qemu-devel] [PATCH RFC] checkpatch: do not warn for multiline parenthesized returned value

[Paolo Bonzini]

While indeed we do not want to have

    return (a);

it is less clear that this applies to

    return (a &&
            b);

Some editors indent more nicely if you have parentheses, and some people's
eyes may appreciate that as well.
