[ Upstream commit 2c41cc0be07b5ee2f1167f41cd8a86fc5b53d82c ]
The call to of_parse_phandle 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/media/platform/qcom/venus/firmware.c:90:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 82, but without a corresponding object release within this function. drivers/media/platform/qcom/venus/firmware.c:94:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 82, but without a corresponding object release within this function. drivers/media/platform/qcom/venus/firmware.c:128:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 82, but without a corresponding object release within this function.
