From 912991aea862c16e85bb7064d42f2c97704c185f Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Mon, 2 Jul 2018 11:08:16 +0200 Subject: [PATCH] powerpc/pseries: Fix missing of_node_put() in rng_init() [ Upstream commit 67c3e59443f5fc77be39e2ce0db75fbfa78c7965 ] The call to of_find_compatible_node() returns a node pointer with refcount incremented thus it must be explicitly decremented here before returning.
