Please see

http://www.kernel.org/doc/Documentation/CodingStyle

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();
}
