Subject[PATCH 4.9 059/139] powerpc/icp-hv: Fix missing of_node_put() in success path
Date
From: Nicholas Mc Guire <hofrat@osadl.org>

[ Upstream commit d3e669f31ec35856f5e85df9224ede5bdbf1bc7b ]

Both of_find_compatible_node() and of_find_node_by_type() will return
a refcounted node on success - thus for the success path the node must
be explicitly released with a of_node_put().

Fixes: 0b05ac6e2480 ("powerpc/xics: Rewrite XICS driver")
