From 353d84c537485500989b190c5af93ad224264e2c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Mon, 3 Oct 2016 00:58:21 +0200 Subject: coccicheck: make transformation for strbuf_addf(sb, "...") more precise We can replace strbuf_addf() calls that just add a simple string with calls to strbuf_addstr() to make the intent clearer. We need to be careful if that string contains printf format specifications like %%, though, as a simple replacement would change the output. Add checks to the semantic patch to make sure we only perform the transformation if the second argument is a string constant (possibly translated) that doesn't contain any percent signs.
