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.
