The display related patches earlier in this series were edited during merge to improve the request unreferencing. Specifically, the need for de-referencing at interrupt time was removed. However, the resulting code did a 'deref(req) ; req = NULL' sequence rather than using the 'req_assign(req, NULL)' wrapper. The two are functionally equivalent, but using the wrapper is more consistent with all the other places where requests are assigned. Note that the whole point of the wrapper is that using it everywhere that request pointers are assigned means that the reference counting is done automatically and can't be accidentally forgotten about. Plus it allows simpler future maintainance if the reference counting mechanisms ever need to change.
