I have never used Coccinelle but yes, sort of. However, you're on the hook for the patch you submit, Coccinelle isn't a person so if you blindly send out a patch Coccinelle generated, without even eyeballing it, you should expect some risk of thrown tomatoes if (unknown to you) this utterly broke some clever code using your previous API in a way you hadn't anticipated in a driver you don't run.
