Ah, I was a bit confused as you had report return 0, which is used by
both errors and warnings.

Would you want something like this:

diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl
index 58848e3..40cbc2f 100755
--- a/scripts/checkpatch.pl
+++ b/scripts/checkpatch.pl
@@ -1109,7 +1109,7 @@ sub ERROR {
 }
 sub WARN {
 	if (report("WARNING: $_[0]\n")) {
-		our $clean = 0;
+		our $clean = 0 if (!$lazy);
 		our $cnt_warn++;
 	}
 }
