Subject: [PATCH 0/6] irqchip: Fix some refcount leaks

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.
