It's not just the "hairy" local macros.

In its current form, checkpatch could not find uses like:

	netif_<foo>(x, y, z,
		    "some string with %pk",
		    args);
and
	some_logging_function(arg, "string 1" CONSTANT "string 2", etc...)

if string 2 or CONSTANT had the "%pk" use.

and a bunch of other styles.

This really needs to be verified by the compiler.
