Subject: [PATCH] powerpc/pseries: Fix missing of_node_put() in rng_init()

References: bsc#1065729
Patch-mainline: v5.10-rc1
Git-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.
