According to Documentation/kernel-doc-nano-HOWTO.txt, these extra braces are
supposed to be present:

"
		Chapter 3: Placing Braces and Spaces
[...]
Do not unnecessarily use braces where a single statement will do.
[...]
This does not apply if only one branch of a conditional statement is a single
statement; in the latter case use braces in both branches:

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