Re: [PATCH 21.5] Static checker fun

APA> Jerry, doesn't instance need to be checked for NULL before APA> dereferencing through it above? Of course, but it already has been checked by the time this function is called. The device methods only get called from a generic method (here free_scrollbar_instance in scrollbar.c), and it's the job of the generic method to check that it's being called on an existing object. Which it does.
