The following patchset fix some refcount leak bugs in irqchip. The cause of the bugs are missing post handling of some APIs ——of_find_node_by_phandle(),of_find_matching_node_and_match(), of_get_child_by_name(). These APIs returns node pointer with refcount incremented. and should use of_node_put() to release it when not needed anymore.
I've sent patch#1 and patch#2 separately before, I move them into one series for better management. the content of them don't change.
