Subject: coccinelle: make use of the "expression" FREE_AND_NULL() rule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A follow-up to the existing "expression" rule added in an earlier
change. This manually excludes a few occurrences, mostly things that
resulted in many FREE_AND_NULL() on one line, that'll be manually
fixed in a subsequent change.
