[PATCH 5.10 094/116] usb: ulpi: Move of_node_put to ulpi_dev_release

[Greg Kroah-Hartman]

From: Sean Anderson <sean.anderson@xxxxxxxx>

commit 092f45b13e51666fe8ecbf2d6cd247aa7e6c1f74 upstream.

Drivers are not unbound from the device when ulpi_unregister_interface
is called. Move of_node-freeing code to ulpi_dev_release which is called
only after all users are gone.
