[ Upstream commit b623fa320f8360f049a6f3c3ccc487cb85af4c5b ]
The call to of_find_compatible_node returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage.
Detected by coccinelle with the following warnings: ./drivers/cpufreq/armada-8k-cpufreq.c:187:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 130, but without a corresponding object release within this function. ./drivers/cpufreq/armada-8k-cpufreq.c:191:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 130, but without a corresponding object release within this function.
