Thanks again for the report. The problem is just the newline before the
(, whch causes the ( to be differently interpreted (for a disjunction).
There is no need for such an interpretation in this position in the code,
so I have updated Coccinelle. The update should be in github by the end
of the day.

Probably we should submit a patch on the semantic patch to add a space in
front of the offending parentheses, to make the rule usable with all
versions.
