3.16.55-rc1 review patch. If anyone has any objections, please let me know.

commit e0638fa400eaccf9fa8060f67140264c4e276552 upstream.
Reference count of device node was increased in of_i2c_register_device, but without decreasing it in i2c_unregister_device. Then the added device node will never be released. Fix this by adding the of_node_put.
