From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxx> [ Upstream commit bd19c4527056b3e42e8c286136660aa14d0b6c90 ] bridge->next is only points to the new bridge if drm_bridge_attach() succeeds. No need to reset it manually here. Note that this change is part of the attempt to make the bridge chain a double-linked list. In order to do that we must patch all drivers manipulating the bridge->next field.
