Based on commit 000d1cc1829f938c ("checkpatch.pl: add
ability to ignore various messages") from Linux kernel.
This simplifies current linux kernel checkpatch.pl commit
adoption for barebox due to conversion of
1-argument ERROR($1), WARN($1) and CHK($1) subs into
2-argument ERROR($1, $2), WARN($1, $2) and CHK($1, $2) subs.
