Subject: of/irq: add missing of_node_put() for interrupt parent node
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=eb2b4ecf7299ee39ee9cecc4d3f2633aeb10cefb;p=linux.git

of/irq: add missing of_node_put() for interrupt parent node

After calling of_irq_parse_one(), the node provided in the of_phandle_args
has a refcount increment by one. Add missing of_node_put in of_irq_get()
to decrement the refcount once used.
