[ Upstream commit ddb64c5db3cc8fb9c1242214d5798b2c2865681c ]
The call to of_node_get 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/imx6q-cpufreq.c:391:4-10: ERROR: missing of_node_put;
acquired a node pointer with refcount incremented on line 348, but without a
corresponding object release within this function.
./drivers/cpufreq/imx6q-cpufreq.c:395:3-9: ERROR: missing of_node_put; acquired
a node pointer with refcount incremented on line 348, but without a
corresponding object release within this function.
