In Coccinelle, you have to specify a complete term. You have only given a
function header. If you mean to be transforming the prototype, then you
should put a ; at the end. If you mean to transform the definition, you
should put { ... } at the end. If you transform the definition, it will
automatically make an extra rule for transforming the prototype.
