There is "Chapter 12: Macros, Enums and RTL" in:
http://www.kernel.org/doc/Documentation/CodingStyle

Some quotes:
1) "Macros with multiple statements should be enclosed in a do - while block:"
2) "macros defining constants using expressions must enclose the
expression in parentheses"

Second one may sound like sth close, but it's just about expressions like:
#define CONSTEXP (CONSTANT | 3)

So there doesn't seem to be any "rule" in CodingStyle wanting us to
add parentheses when you suggested.
