So, for this piece of code:

TRACE_EVENT(...

	TP_fast_assign(
		__entry->foo = bar( xxx );
	),
)

checkpatch won't report the spaces inside bar()?
If so, I don't like this patch.

Could you just teach checkpatch to recognize those macros used
in TRACE_EVENT(), if those coding-style "errors" bother you
so much that you can't put up with them?
