Boot fails for qcom-apq8074-dragonboard on 4.13-rc1 with error:
OF: ERROR: Bad of_node_put() on /soc/usb@f9a55000
The error will occur if the configuration is set to:
CONFIG_OF_OVERLAY y
CONFIG_OF_UNITTEST y
CONFIG_OF_DYNAMIC y
CONFIG_OF_RESOLVE y
If CONFIG_OF_DYNAMIC is enabled then of_node_release() detects an
attempt to release a node that is still attached to the device tree.
