Subject[PATCH] cpufreq: zynq: Fix refcount leak in zynq_get_revision
Date
of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Fixes: 00f7dc636366 ("ARM: zynq: Add support for SOC_BUS")
