Maxime Ripard b784c77075 coccinnelle: Remove ptr_ret script ... The ptr_ret script script addresses a number of situations where we end up testing an error pointer, and if it's an error returning it, or return 0 otherwise to transform it into a PTR_ERR_OR_ZERO call. So it will convert a block like this: if (IS_ERR(err)) return PTR_ERR(err); return 0; into return PTR_ERR_OR_ZERO(err); While this is technically correct, it has a number of drawbacks. First, it merges the error and success path, which will make it harder for a reviewer or reader to grasp. It's also more difficult to extend if we were to add some code between the error check and the function return, making the author essentially revert that patch before adding new lines, while it would have been a trivial addition otherwise for the rewiever. Therefore, since that script is only about cosmetic in the first place, let's remove it since it's not worth it.
