I haven't tried checkpatch.pl over that file, but in the CodingStyle
document you can read this:

Do not unnecessarily use braces where a single statement will do.

if (condition)
        action();

This does not apply if one branch of a conditional statement is a single
statement. Use braces in both branches.

if (condition) {
        do_this();
        do_that();
} else {
        otherwise();
}

Which one is the correct style? I ask these because I have seen this
in other parts of the kernel. So maybe I can help to homogenize this.

I believe only this one has to go.

So the first brace closes the brace of the if line.
