[PATCH 5.9 402/757] powerpc/icp-hv: Fix missing of_node_put() in success path

From: Greg Kroah-Hartman
Date: Tue Oct 27 2020 - 11:47:13 EST


From: Nicholas Mc Guire <hofrat@xxxxxxxxx>

[ 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().
