Subject: [PATCH AUTOSEL 4.19 19/22] mips: lantiq: Add missing of_node_put() in irq.c

From: Liang He <windhl@....com>

[ Upstream commit 3748d2185ac4c2c6f80989672253aad909ecaf95 ]

In icu_of_init(), of_find_compatible_node() will return a node
pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.
